+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+# What is Gobbledegook?
+
+_Gobbledegook_ is a standalone D-Bus-based BlueZ BLE GATT server for Linux with HCI support and a simple C interface. That's a lot of words, so I shortened it to _Gobbledegook_. Then I shortened it again to _GGK_ because let's be honest, it's a pain to type.
+
+For the impatient folks in a hurry (or really just have to pee) skip down to the **Quick-start for the impatient** section at the bottom of this document.
+
+### Features
+
+* DSL-like creation of BLE services makes creating services trivial
+* Automated D-Bus object hierarchy introspection generation
+* Automated D-Bus ObjectManager implementation
+* Automated BlueZ GATT application registration
+* Support for the [Bluetooth Management API](https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/mgmt-api.txt)
+* Timer events allow services to perform periodic updates
+* Application-managed server data
+* Comment blocks at the top of each source file with deep explanations of critical concepts
+* Written in C++14 (gcc & clang) with a standard C public interface
+* Tested on Ubuntu 16.04 on x86 and Raspberry Pi
+
+# Server description
+
+A *server description* is the meat of your server. It is a collection one or more GATT Services. Each GATT Service contains a collection of one or more characteristics, which in turn may contain zero or more descriptors. The server description is declared in the `Server` constructor found in `Server.cpp`.
+
+The following sections explain how to build a server description.
+
+> **New to Bluetooth terminology?**
+>
+> **Bluetooth Low Energy** (or **BLE**) is the marketing term for Bluetooth 4.0. A *BLE* server will offer up one or more *GATT Services*.
+>
+> **GATT** stands for Generic Attribute Profile (apparently the *P* is silent.) This is the standard that defines how BLE devices share data. Specifically, it defines the structure of services, characteristics and descriptors.
+>
+>A **GATT Service** can be thought of as a discreet unit of functionality. Examples would be a *time service* that returns the current local time and timezone or a *battery service* that returns the current battery level and temperature. A *GATT Service* serves up information in the form of a collection of one or more *GATT Characteristics*.
+>
+>A **GATT Characteristic** is one unit of data from a GATT Service. For example, our fictitious *battery service* would have two *GATT Characteristics*: (1) the current battery level and (2) the temperature. The battery level characteristic might be defined as a single byte value in the range of 0-100 representing the percentage of battery remaining. In addition to their data, a *GATT Characteristic* may also contain zero or more optional *GATT Descriptors*.
+>
+> A **GATT Descriptor** contains additional information and metadata about a *GATT Characteristic*. They can be used to describe the characteristic's features or to control certain behaviors of the characteristic. Extending our *battery service* example further, the temperature characteristic could be a 16-bit value representing a temperature, while the *GATT Descriptor* further defines how to interpret that data (as degrees Fahrenheit, degrees Celsius or 10th of degrees Kelvin.)
+
+### Implementing services with GGK
+
+Below is a complete custom GATT Service as defined within the GGK framework. It is a simple service that uses the `asctime()` function to return the current time as a string:
+
+```c++
+// Create a service
+.gattServiceBegin("ascii_time", "00000001-1E3D-FAD4-74E2-97A033F1BFEE")
+
+ // Add a characteristic to the service with the 'read' flag set
+ .gattCharacteristicBegin("string", "00000002-1E3D-FAD4-74E2-97A033F1BFEE", {"read"})
+
+ // Handle the characteristic's "ReadValue" method
+ .onReadValue(CHARACTERISTIC_METHOD_CALLBACK_LAMBDA
+ {
+ time_t timeVal = time(nullptr);
+ struct tm *pTimeStruct = localtime(&timeVal);
+ std::string timeString = asctime(pTimeStruct);
+ self.methodReturnValue(pInvocation, timeString, true);
+ })
+
+ .gattCharacteristicEnd()
+
+.gattServiceEnd()
+```
+
+The first thing you may notice about this example is that many of the lines begin with a dot. This is because we're chaining methods together. Each method returns the appropriate type to provide *context*. Internally the `gattServiceBegin()` method returns a reference to a `GattService` object which provides the proper context to create a characteristic within that service. Similarly, the `gattCharacteristicBegin()` method returns a reference to a `GattCharacteristic` object which provides the proper context for responding to the `onReadValue()` method or adding descriptors to the characteristic.
+
+You may also have noticed that we're using lambdas to include our implementation inline. The code to generate the time string is wrapped up in a `CHARACTERISTIC_METHOD_CALLBACK_LAMBDA` which is just a convenience macro that declares the lambda properly for us. You can use the raw lambda declaration if you wish, but then you're being anti-macroist and that's just not cool, bruh. And if you don't like these new-fangled lambdas, you can just stick a good ol' function pointer in its place.
+
+>#### *Side note*
+>
+>A compiled GGK library provides a public interface that is compatible with standard C, but you'll need a modern compiler to build a GGK library because the internals are written using features of c++11.
+
+Let's take a look at a more complex example. Here's an implementation of the Bluetooth standard's [Current Time Service](https://www.bluetooth.com/specifications/gatt/viewer?attributeXmlFile=org.bluetooth.service.current_time.xml). We'll even toss a few extras in to keep things interesting:
+
+```c++
+// Current Time Service (0x1805)
+.gattServiceBegin("time", "1805")
+ .gattCharacteristicBegin("current", "2A2B", {"read", "notify"})
+ .onReadValue(CHARACTERISTIC_METHOD_CALLBACK_LAMBDA
+ {
+ self.methodReturnVariant(pInvocation, ServerUtils::gvariantCurrentTime(), true);
+ })
+ .gattDescriptorBegin("description", "2901", {"read"})
+ .onReadValue(DESCRIPTOR_METHOD_CALLBACK_LAMBDA
+ {
+ self.methodReturnValue(pInvocation, "Current server local time", true);
+ })
+ .gattDescriptorEnd()
+ .onEvent(60, nullptr, CHARACTERISTIC_EVENT_CALLBACK_LAMBDA
+ {
+ self.sendChangeNotificationVariant(pConnection, ServerUtils::gvariantCurrentTime());
+ })
+ .gattCharacteristicEnd()
+ .gattCharacteristicBegin("local", "2A0F", {"read"})
+ .onReadValue(CHARACTERISTIC_METHOD_CALLBACK_LAMBDA
+ {
+ self.methodReturnVariant(pInvocation, ServerUtils::gvariantLocalTime(), true);
+ })
+ .gattDescriptorBegin("description", "2901", {"read"})
+ .onReadValue(DESCRIPTOR_METHOD_CALLBACK_LAMBDA
+ {
+ self.methodReturnValue(pInvocation, "Local time data", true);
+ })
+ .gattDescriptorEnd()
+ .gattCharacteristicEnd()
+.gattServiceEnd()
+```
+
+If you're already familiar with BLE, then hopefully the expansion to multiple characteristics and the addition of descriptors needs no further explanation. If that's true, then you're probably amazed by that. Maybe a more modest level of amazement than it's-bigger-on-the-inside amazement levels, but you should still be sure to catch your breath before trying to read further. Safety first.
+
+Did you notice the bonus call to `onEvent()`? The event (a `TickEvent` to be specific) is not part of the Bluetooth standard. It works similar to a typical GUI timer event. In this example, we're using it to send out a change notification (a "PropertiesChanged" notification in the standard parlance). Any client that has subscribed to that characteristic will receive an updated time every 60 ticks (seconds.)
+
+### Contexts
+
+Working in hierarchical contexts of *services*, *characteristics*, *descriptors* and *methods* simplifies the process building a server description because each context has a limited set of available tools to work with. For example, within a *service* context the only tools available are `gattCharacteristicBegin()` and `gattServiceEnd()`. This isn't a limitation on your flexibility; anything else would be a deviation from the [specification](https://git.kernel.org/pub/scm/bluetooth/bluez.git/plain/doc/gatt-api.txt).
+
+>#### *TIP: A context is a scope*
+>
+>A GGK *context* is a synonym for the C term *scope*.
+>
+>The *Service context* is another way of saying the *`GattService` object scope*. Similarly, *Characteristics* and *Descriptors* are scopes of the `GattCharacteristic` and `GattDescriptor` objects.
+>
+>*Methods* differ slightly in that they are scoped to their lambdas. However, *Methods* also contain a `self` parameter which is a reference to the containing scope. In other words, a *Method* within a *Descriptor* will have a `self` reference to the `GattDescriptor` object where that method is declared. More on this in the **Lambda reference** section.
+
+### Service cheat sheet
+
+GATT Services are chained together to form a complete *server description*. So let's focus on how a GATT Service is built.
+
+Below is a template for a GATT Service with all available components. Function parameters are shown by name and indentation denotes context.
+
+Note that a service may contain more than one characteristic, in which case they would follow each other sequentially within the service description. The same holds true for Descriptors, except that a characteristic may have no descriptors. In addition, each of the four methods found in the characteristics and descriptors (`.onEvent()`, `.onReadValue()`, `.onWriteValue()` and `.onUpdateValue()`) would only be present if needed.
+
+ .gattServiceBegin(name, uuid)
+ .gattCharacteristicBegin(name, uuid, flags[])
+ .onEvent(tickFrequency, userData, CHARACTERISTIC_EVENT_CALLBACK_LAMBDA
+ {
+ [...your code here...]
+ })
+ .onReadValue(CHARACTERISTIC_METHOD_CALLBACK_LAMBDA
+ {
+ [...your code here...]
+ })
+ .onWriteValue(CHARACTERISTIC_METHOD_CALLBACK_LAMBDA
+ {
+ [...your code here...]
+ })
+ .onUpdatedValue(CHARACTERISTIC_UPDATED_VALUE_CALLBACK_LAMBDA
+ {
+ [...your code here...]
+ })
+ .gattDescriptorBegin(name, uuid, flags[])
+ .onEvent(tickFrequency, userData, DESCRIPTOR_EVENT_CALLBACK_LAMBDA
+ {
+ [...your code here...]
+ })
+ .onReadValue(DESCRIPTOR_METHOD_CALLBACK_LAMBDA
+ {
+ [...your code here...]
+ })
+ .onWriteValue(DESCRIPTOR_METHOD_CALLBACK_LAMBDA
+ {
+ [...your code here...]
+ })
+ .onUpdatedValue(DESCRIPTOR_UPDATED_VALUE_CALLBACK_LAMBDA
+ {
+ [...your code here...]
+ })
+ .gattDescriptorEnd()
+ .gattCharacteristicEnd()
+ .gattServiceEnd()
+
+# Method reference
+
+The following methods are available within the context of either a characteristic or descriptor.
+
+---
+### `onReadValue(callback_or_lambda)`
+
+Register a lambda or callback that is called whenever a Bluetooth client reads the value of a characteristic or descriptor. It is tied to the `ReadValue` method described in the [BlueZ D-Bus GATT API](https://git.kernel.org/pub/scm/bluetooth/bluez.git/plain/doc/gatt-api.txt).
+
+---
+### `onWriteValue(callback_or_lambda)`
+
+Register a lambda or callback that is called whenever a Bluetooth client writes to the value of a characteristic or descriptor. It is tied to the `WriteValue` method described in the [BlueZ D-Bus GATT API](https://git.kernel.org/pub/scm/bluetooth/bluez.git/plain/doc/gatt-api.txt).
+
+---
+### `onEvent(int tickFrequency, void *pUserData, callback_or_lambda)`
+
+Register a lambda or callback that is called after `tickFrequency` ticks of the periodic timer. Tick events work similar to timer events found in modern GUIs.
+
+Events can be used to update server data, send notifications or perform any other general periodic work. This is a convenience method of GGK and is not part of the Bluetooth standard or BlueZ D-Bus GATT API.
+
+---
+### `onUpdatedValue(callback_or_lambda)`
+
+Register a lambda or callback that is called when data is updated internally by the application.
+
+As an application generates or updates its own data, it may notify the server of those updates using the public interface methods `ggkNofifyUpdatedCharacteristic()` and `ggkNofifyUpdatedDescriptor()`. The server will then call the appropriate `onUpdateValue` lambda or callback for the characteristic or descriptor receiving the update. This is a convenience method of GGK and is not part of the Bluetooth standard or BlueZ D-Bus GATT API.
+
+Aside from the application performing data updates, a characteristic or descriptor may modify its own data from within a lambda and trigger this call. For details, see `self.callOnUpdatedValue()` method in the **Lambda reference** section below.
+
+# Lambda reference
+
+Within the context of a lambda there is a `self` parameter that references the parent context (the characteristic or descriptor under which the lambda is registered.)
+
+The following methods are available to through that `self` parameter.
+
+---
+#### `T self.getDataValue(const char *name, const T default)`
+
+Gets a named value from the server data (see the section **Server data** for details on how this data is managed.) If `name` is not found, `default` is returned. This is a templated function to allow non-pointer data of any type to be retrieved. For pointer data, see `self.getDataPointer()`.

This is a templated function to allow pointer data of any type to be retrieved. Note that `T` is a pointer type. For non-pointer values, see `self.getDataValue()`.
+
+---
+#### `bool self.setDataValue(const char *name, const T value)`
+
+Sets the named `value` in the server data (see the section **Server data** for details on how this data is managed.) This is a templated function to allow non-pointer data of any type to be set. For pointer data, see `self.setDataPointer()`.

+
+Send a value to a Bluetooth client in response to a method call (such as `ReadValue`).
+
+Unlike normal return values from methods within a program, return values in response to Bluetooth method calls must be explicitly sent.
+
+This is a templated function to allow common data types to be automatically placed into a GVariant array of bytes ("ay") with the option of wrapping the response in a tuple ("(ay)"). For a generic `GVariant *` version of this method, see `methodReturnVariant()`.
+
+For information on GVariants, see the [GLib reference manual](https://www.freedesktop.org/software/gstreamer-sdk/data/docs/latest/glib/).

+#### `void self.methodReturnVariant(self.pInvocation, GVariant *pVariant, bool wrapInTuple = false)`
+
+Send a `GVariant` to a Bluetooth client in response to a method call (such as `ReadValue`).
+
+Unlike normal return values from methods within a program, return values in response to Bluetooth method calls must be explicitly sent.
+
+If `wrapInTuple` is set to true, the `pVariant` is automatically wrapped in a tuple before sending. A convenience function is available for responding with common data types (see `methodReturnValue()`).

+
+Sends a change notification (in BlueZ parlance, a "PropertiesChanged" signal) with an updated `GVariant *` value to subscribers to this characteristic.
+
+This is a generalized method that accepts a `GVariant *`. A templated version is available that supports common types called `sendChangeNotificationValue()`.
+
+For information on GVariants, see the [GLib reference manual](https://www.freedesktop.org/software/gstreamer-sdk/data/docs/latest/glib/).

+
+# Server Data
+
+Server data is maintained by the application. When the application starts the GGK server, it calls `ggkStart()` with two delegates: a data getter and a data setter. These methods are used by the server to retrieve and store server data.
+
+For details on these delegates and their usage, see the comment blocks in `Gobbledegook.h` under the section heading `SERVER DATA`.
+
+# A brief look under the hood
+
+When we build a server description, what we're really doing is building a hierarchical structure of D-Bus objects that conforms to [BlueZ's standards for GATT services](https://git.kernel.org/pub/scm/bluetooth/bluez.git/plain/doc/gatt-api.txt). The `*Begin()` and `*End()` calls are the building blocks for this hierarchy.
+
+GGK uses this server description to build an [XML introspection](https://dbus.freedesktop.org/doc/dbus-specification.html#introspection-format) used to register the object hierarchy with D-Bus. You can view the generated XML for your services by launching the `standalone` application with the `-d` parameter.
+
+GGK also uses the server description to implement the [D-Bus ObjectManager](https://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-objectmanager) interface which is used to describe our services. When we eventually register our application with BlueZ, BlueZ will use our ObjectManager interface to enumerate our services. GGK manages this for us automatically.
+
+# System configuration tips
+
+The following sections may help users with their system configurations.
+
+### BlueZ Version
+
+My distribution didn't have the latest version of BlueZ with proper support for their D-Bus API (it was still considered experimental up until v5.42.) I had to download and build it for myself. I grabbed BlueZ 5.45.
+
+Here's how I built it - this will probably work for most or all Ubuntu users:
+
+ ./configure --prefix=/usr --libexecdir=/usr/lib \
+ --sysconfdir=/etc --localstatedir=/var --enable-test \
+ --enable-manpages --enable-testing --enable-library \
+ --enable-maintainer-mode --enable-experimental \
+ --enable-deprecated
+ make
+ service bluetooth stop
+ sudo make install # Helpful for development
+ systemctl daemon-reload # Helpful for development
+ service bluetooth start # Helpful for development
+
+If you're on a Raspberry Pi, you should probably also run `sudo rpi-update` followed by a reboot.
+
+### Configuring BlueZ
+
+The configuration file is located at `/etc/bluetooth/main.conf`. However, you should be fine with defaults here because this server can configure the settings as needed.
+
+### Enable BlueZ debug logs
+
+Edit the file `/lib/systemd/system/bluetooth.service` and set the `ExecStart` line to look like:
+
+ ExecStart=/usr/lib/bluetooth/bluetoothd -d --noplugin=hostname
+
+**`-d`** - it's a good idea to leave this enabled while you are setting up your services in GGK (you can remove it later). This will allow you to `tail -f /var/log/syslog | grep bluetoothd` to get some helpful debug information.
+
+**`--noplugin=hostname`** - this prevents BlueZ from running the 'hostname' plugin, which will rename your device to whatever its hostname is (ignoring your configurations.)
+
+Once you've done this, run the following commands to reload these settings and restart the service:
+
+ sudo systemctl daemon-reload
+ sudo service bluetooth stop
+ sudo service bluetooth start
+
+### Enabling Bluetooth
+
+You don't need to do anything. this server will automatically power on the adapter, enable LE with advertisement.
+
+However, if you want to do this manually, here are a few helpful commands you might try:
+
+ sudo btmgmt -i 0 power off
+ sudo btmgmt -i 0 le on
+ sudo btmgmt -i 0 connectable on
+ sudo btmgmt -i 0 advertising on
+ sudo btmgmt -i 0 power on
+
+# Build & Launch
+
+GGK uses the standard autotools build process:
+
+ ./configure && make
+
+This will build `libggk.a` then compile `standalone.cpp` into a program that links with `libggk.a`. There is no `make install` as there is nothing to install.
+
+Then run with:
+
+ sudo src/standalone -d
+
+GGK requires super-user privileges when run due to privileges required for D-Bus and HCI sockets. A system can be configured to allow a user to run a GGK server without `sudo`, but that's beyond the scope of this document.
+
+During development, I tend to run these three commands, each in their own terminal:
+
+ sudo tail -f /var/log/syslog | grep bluetoothd
+ sudo dbus-monitor --system
+ sudo ./src/standalone -d
+
+With no parameters, `standalone` will output only service level output (starting stopping errors, etc.) Additional output parameters are:
+
+ `-q` Quiet - errors only
+ `-v` Verbose - include info log levels
+ `-d` Debug - include debug log levels
+
+# Testing your server
+
+If you don't already have some kind of test harness, you'll probably want something. I've had luck with a free Android app called *nRF Connect*.
+
+# Integration into your own app
+
+Think of Gobbledegook as a template BLE library. You're expected to modify `Server.cpp` and replace the example services with your own. Once you've customized your services, the rest is easy.
+
+Just link against `libggk.a` and include `include/Gobbledegook.h` to access the public API in your app. You may notice that the public interface isn't documented here. Instead, it is documented in `include/Gobbledegook.h`.
+
+You can use `standalone.cpp` as a reference on how to get things setup in your code.
+
+# Other handy references
+
+If you decide to dig into the codebase, you'll want to be familiar with D-Bus. If you've never messed with D-Bus, this short [Introduction to D-Bus](https://www.freedesktop.org/wiki/IntroductionToDBus/) will help a lot. GGK uses GLib's GIO for all D-Bus work, which is fully documented in the [GIO Reference Manual](https://developer.gnome.org/gio/stable/). And finally, for the real nitty-gritty on D-Bus be sure to visit the [D-Bus Specification](https://dbus.freedesktop.org/doc/dbus-specification.html).
+
+The [BlueZ D-Bus APIs](https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc) are fully documented. They're brief, but complete. Pay special attention to the [BlueZ D-Bus GATT API description](https://git.kernel.org/pub/scm/bluetooth/bluez.git/plain/doc/gatt-api.txt), which describes how GATT services are implemented over D-Bus.
+
+The [GLib Reference Manual](https://developer.gnome.org/glib/stable/) covers many topics used in GGK, most notably the use of `GVariant` objects for passing data around over D-Bus. Pay special attention to the [GVariant Format Strings](https://developer.gnome.org/glib/stable/gvariant-format-strings.html) page.
+
+# Reference output
+
+The following is the output from a reference tool used to connect to the `standalone` server running with the sample services. The output shows data read from the server over BLE. Note that the hieararchy may not match 1:1 with that of the samples, since some features are automatically provided by BlueZ. In addition, the reference tool periodically writes updates to the `Text string` service (hence the appended text, *"(updated: 3 times)"*.)

+# Quick-start for the impatient
+
+**Build** with `./configure && make`. This will build `libggk.a` then compile `standalone.cpp` into a program that links with `libggk.a`.
+
+**Run** `sudo ./src/standalone -d`. This will require your machine to be setup correctly with `BlueZ` and working BLE hardware. Don't forget the `sudo`; you'll need it unless you configure the appropriate permissions for your user to access to D-Bus and the HCI socket. Options are: `-e` (errors-only output), `-v` (verbose output), `-d` (debug output)
+
+**Coding** your own BLE services is actually very easy once you become a little familiar with things. Think of Gobbledegook as a template BLE library. You're expected to modify `Server.cpp` and replace the example services with your own. Do yourself a favor and scan through the **Implementing services with GGK** section. It's your quickest path to understanding the foundation.
+
+**Integrating** into your app is easy: just link against `libggk.a` and include `include/Gobbledegook.h` where needed. Use `standalone.cpp` as a template for getting things setup in your code. \ No newline at end of file

+# SYNOPSIS
+#
+# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+# Check for baseline language coverage in the compiler for the specified
+# version of the C++ standard. If necessary, add switches to CXX and
+# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard)
+# or '14' (for the C++14 standard).
+#
+# The second argument, if specified, indicates whether you insist on an
+# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+# -std=c++11). If neither is specified, you get whatever works, with
+# preference for an extended mode.
+#
+# The third argument, if specified 'mandatory' or if left unspecified,
+# indicates that baseline support for the specified C++ standard is
+# required and that the macro should error out if no mode with that
+# support is found. If specified 'optional', then configuration proceeds
+# regardless, after defining HAVE_CXX${VERSION} if and only if a
+# supporting mode is found.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+// This file represents the complete interface to Gobbledegook from a stand-alone application.
+//
+// >>
+// >>> DISCUSSION
+// >>
+//
+// The interface to Gobbledegook is rether simple. It consists of the following categories of functionality:
+//
+// * Logging
+//
+// The server defers all logging to the application. The application registers a set of logging delegates (one for each
+// log level) so it can manage the logs however it wants (syslog, console, file, an external logging service, etc.)
+//
+// * Managing updates to server data
+//
+// The application is required to implement two delegates (`GGKServerDataGetter` and `GGKServerDataSetter`) for sharing data
+// with the server. See standalone.cpp for an example of how this is done.
+//
+// In addition, the server provides a thread-safe queue for notifications of data updates to the server. Generally, the only
+// methods an application will need to call are `ggkNofifyUpdatedCharacteristic` and `ggkNofifyUpdatedDescriptor`. The other
+// methods are provided in case an application requies extended functionality.
+//
+// * Server control
+//
+// A small set of methods for starting and stopping the server.
+//
+// * Server state
+//
+// These routines allow the application to query the server's current state. The server runs through these states during its
+// lifecycle:
+//
+// EUninitialized -> EInitializing -> ERunning -> EStopping -> EStopped
+//
+// * Server health
+//
+// The server maintains its own health information. The states are:
+//
+// EOk - the server is A-OK
+// EFailedInit - the server had a failure prior to the ERunning state
+// EFailedRun - the server had a failure during the ERunning state

+// >>
+// >>> DISCUSSION
+// >>
+//
+// Not sure what a D-Bus Interface is? Well, chedk the Readme for resources, but here's the TL;DR:
+//
+// A D-Bus interface is a contract (similar to programming language interfaces.) An interface defines a set of methods and
+// properties for others to use.
+//
+// Interfaces are identified by their name, such as "org.freedesktop.DBus.Properties". In fact, if an object on the bus is found
+// to have that interface, then you know that it provides an interface to access its properties via the methods "Get", "GetAll" and
+// "Set". To see the details for this interface (and all of the D-Bus defined interfaces), see:
+//
+// https://dbus.freedesktop.org/doc/dbus-specification.html
+//
+// We're also interested in working with BlueZ which has their own set of interfaces. One example is "org.bluez.GattManager1" which
+// is the interface used to create and register GATT services with BlueZ.
+//
+// Remember, interfaces are not implementations; they're just contracts to provide an implementation. That means some interfaces
+// are intended for us to implement. One example is "org.bluez.GattService1" which defines the interface that we must conform to
+// so that others (likely BlueZ) can access our GATT service(s). For more information on these, have a look at:
+//
+// https://git.kernel.org/pub/scm/bluetooth/bluez.git/plain/doc/gatt-api.txt
+//
+// Our interfaces also store a collection of events. Here, an event is much like a timer in modern UIs, which repeatedly fires
+// after a defined time. A practical example of an event would be a BLE server that provides a Battery service. By adding a timer
+// to the interface for this service, the server could wake up every minute to check the battery level and if it has changed, send
+// a notifications to clients over BLE with the new battery level. This saves a lot of additional code on the server's part.

+//
+// A D-Bus object is a container for any number of functional interfaces to expose on the bus. Objects are referred to by their
+// path ("/com/acme/widgets"). Here is a simple example of how D-Bus objects relate to Bluetooth services:
+//
+// Object (path) Interface (name)
+//
+// /com/acme/widget org.bluez.GattService1
+// /com/acme/widget/manufacturer_name org.bluez.GattCharacteristic1
+// /com/acme/widget/serial_number org.bluez.GattCharacteristic1
+//
+// In English, this would be read as "The Acme company has a widget, which has two characteristics defining the manufacturer name
+// and serial number for the widget."
+//
+// Finally, we'll include a published flag. Here's what that's all about:
+//
+// BlueZ uses the GetManagedObjects method (from the org.freedesktop.DBus.ObjectManager interface) to interrogate our
+// service(s). Our Server, however, includes all objects and interfaces, including the GetManagedObjects as well as the various
+// interfaces we expose over Bluetooth. Therefore, we'll need a way to know which ones to expose over Bluetooth (which is, in
+// general, everything EXCEPT the object containing the org.freedesktop.DBus.ObjectManager interface.) Since we manage our
+// objects in a hierarchy, only the root object's publish flag matters.

+// >>> DISCUSSION
+// >>
+//
+// A GATT UUID represents a unique identifier for a GATT service, characteristic or descriptor. UUIDs allow clients to recognize
+// the purpose of a service (battery level, temperature data, etc.) Similarly, they are used to identify characteristics (the
+// battery percentage or actual temperature value) and descriptors (for example, the format of a characteristic data item.)
+//
+// GATT UUIDs come in three flavors: 16-bit, 32-bit and 128-bit. In practice, you will see two different kinds of UUIDs: a short
+// UUID (ex: "2901") and a long UUID (ex: "00000002-1E3C-FAD4-74E2-97A033F1BFAA").
+//
+// The short form refer to 16-bit UUID that is assigned to a standard interface defined as part of the Bluetooth Wireless Standard.
+// The short UUID "2901" refers to a standard (assigned by the Bluetooth Wireless Standard) descriptor named "Characteristic User
+// Description". These are commonly called "Assigned Numbers".
+//
+// In fact, all UUIDs are 128-bit values. The 16-bit form is just an abbreviated way of specifying a standard interface that uses
+// what Bluetooth calls the "Base Universally Unique Identifier (UUID)". This UUID is defined by the standard as
+// "00000000-0000-1000-8000-00805f9b34fb". The 16-bit value "2901" would be inserted into the Base UUID like so:
+// "00002901-0000-1000-8000-00805f9b34fb".
+//
+// When defining a custom service (or characteristic or descriptor) UUIDs are typically generated by the developer. These UUIDs are
+// then used by the client software to recognize the custom service (or characteristic or descriptor.)
+//
+// The `GattUuid` class is a helper class for creating instances of UUIDs. By instantiating a GattUuid with a 4-character string,
+// the GattUuid will treat the string as a 16-bit UUID and wrap it with the Base Universally Unique Identifier. Similarly, an 8-
+// character string will be treated as a standard 32-bit UUID, also wrapping it with the Base Universally Unique Identifier. A 32-
+// character string will be treated as a 128-bit GATT UUID.
+//
+// When specifying your UUIDs, feel free to use the format that suits you best (with or without dashes, dots in place of dashes,
+// etc.) The string will first be sanitized, removing all non-hex characters, and then re-formatted appropriately with the dashes
+// in their standard places: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx".
+//
+// By represetng a UUID in a custom class like this, we are able to give a UUID its own type, and use type safety to ensure that we
+// don't confuse regular strings with GATT UUIDs throughout the codebase.

+//
+// Although Gobbledegook requires customization (see Server.cpp), it still maintains a public interface (this file.) This keeps the
+// interface to the server simple and compact, while also allowing the server to be built as a library if the developer so chooses.
+//
+// As an alternative, it is also possible to publish customized Gobbledegook servers, allowing others to use the server through the

+//
+// In addition, this interface is compatible with the C language, allowing non-C++ programs to interface with Gobbledegook, even
+// though Gobbledgook is a C++ codebase. This should also simplify the use of this interface with other languages, such as Swift.
+//
+// The interface below has the following categories:
+//
+// Log registration - used to register methods that accept all Gobbledegook logs
+// Update queue management - used for notifying the server that data has been updated
+// Server state - used to track the server's current running state and health

+//
+// >>
+// >>> DISCUSSION
+// >>
+//
+// This class is intended for use by `Mgmt` (see Mgmt.cpp).
+//
+// The Bluetooth Management API, is used to configure the Bluetooth adapter (such as enabling LE, setting the device name, etc.)
+// This class uses HciSocket (HciSocket.h) for the raw communications.
+//
+// The information for this implementation (as well as HciSocket.h) came from:
+//
+// https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/mgmt-api.txt
+//
+// KNOWN LIMITATIONS:
+//
+// This is far from a complete implementation. I'm not even sure how reliable of an implementation this is. However, I can say with
+// _complete_confidence_ that it works on my machine after numerous minutes of testing.
+//
+// One notable limitation is that this code doesn't work with the Bluetooth Management API in the way it was intended. The Bluetooth
+// Management API treats the sending and receiving of data differently. It receives commands on the HCI socket and acts upon them.
+// It also sends events on the same socket. It is important to note that there is not necessarily a 1:1 correlation from commands
+// received to events generated. For example, an event can be generated when a bluetooth client disconnects, even though no command
+// was sent for which that event is associated.
+//
+// However, for initialization, it seems to be generally safe to treat them as "nearly 1:1". The solution below is to consume all

+// This is our Logger, which allows for applications to use their own logging mechanisms by registering log receivers for each of
+// the logging categories.
+//
+// >>
+// >>> DISCUSSION
+// >>
+//
+// In order for logging to work, the application must register logging receivers with the `ggkLogRegister*` methods. At that point,
+// it is up to the application to decide how to handle the incoming log requests. For example, it may filter Error and Fatal logs
+// to stderr.
+//
+// The following is a breakdown of the intended use of each of the available categories. Application receivers can filter then
+// (enable/ disable/redirect/etc.) in whatever way works best (via bitmasks, log levels, etc.)
+//
+// Debug - Lowest logging level; may contain log-spam
+// Info - The logging equivalent to the junk drawer
+// Status - Current health/service availability info (ex: "Server starting", "Initialization complete", "Stop requested")
+// Warn - Problems that may or may not affect functionality
+// Error - Problems that will affect functionality, but do not result in a termination of the process
+// Fatal - Issues that so severe as to require termination
+//
+// The following log categories should be considered very important (and possibly never filtered):
+//
+// Always - Use when something absolutely, positively has to show up in the log output
+// Trace - Useful for tracing through code (ex: "Before call to foo()", "Entering function bar") and other development use
+// only and should be removed before a release.
+//
+// Using the logger is simple:
+//

+// >>> INSIDE THIS FILE
+// >>
+//
+// This is the money file. This is your server description and complete implementation. If you want to add or remove a Bluetooth
+// service, alter its behavior, add or remove characteristics or descriptors (and more), then this is your new home.
+//
+// >>
+// >>> DISCUSSION
+// >>
+//
+// The use of the term 'server', as it is used here, refers a collection of BlueZ services, characteristics & Descripors (plus
+// a little more.)
+//
+// Our server needs to be described in two ways. Why two? Well, think about it like this: We're communicating with Bluetooth
+// clients through BlueZ, and we're communicating with BlueZ through D-Bus. In essence, BlueZ and D-Bus are acting as tunnels, one
+// inside the other.
+//
+// Here are those two descriptions in a bit more detail:
+//
+// 1. We need to describe ourselves as a citizen on D-Bus: The objects we implement, interfaces we provide, methods we handle, etc.
+//
+// To accomplish this, we need to build an XML description (called an 'Introspection' for the curious readers) of our DBus
+// object hierarchy. The code for the XML generation starts in DBusObject.cpp (see `generateIntrospectionXML`) and carries on
+// throughout the other DBus* files (and even a few Gatt* files).
+//
+// 2. We also need to describe ourselves as a Bluetooth citizen: The services we provide, our characteristics and descriptors.
+//
+// To accomplish this, BlueZ requires us to implement a standard D-Bus interface ('org.freedesktop.DBus.ObjectManager'). This
+// interface includes a D-Bus method 'GetManagedObjects', which is just a standardized way for somebody (say... BlueZ) to ask a
+// D-Bus entity (say... this server) to enumerate itself. This is how BlueZ figures out what services we offer. BlueZ will
+// essentially forward this information to Bluetooth clients.
+//
+// Although these two descriptions work at different levels, the two need to be kept in sync. In addition, we will also need to act
+// on the messages we receive from our Bluetooth clients (through BlueZ, through D-Bus.) This means that we'll have yet another
+// synchronization issue to resolve, which is to ensure that whatever has been asked of us, makes its way to the correct code in
+// our description so we do the right thing.
+//
+// I don't know about you, but when dealing with data and the concepts "multiple" and "kept in sync" come into play, my spidey
+// sense starts to tingle. The best way to ensure sychronization is to remove the need to keep things sychronized.
+//
+// The large code block below defines a description that includes all the information about our server in a way that can be easily
+// used to generate both: (1) the D-Bus object hierarchy and (2) the BlueZ services that occupy that hierarchy. In addition, we'll
+// take that a step further by including the implementation right inside the description. Everything in one place.
+//
+// Well, almost one place (hint: Take a quick look at Globals.h - that's where your server name is.)
+//
+// >>
+// >>> MANAGING SERVER DATA
+// >>
+//
+// The purpose of the server is to serve data. Your application is responsible for providing that data to the server via two data
+// accessors (a getter and a setter) that implemented in the form of delegates that are passed into the `ggkStart()` method.
+//
+// While the server is running, if data is updated via a write operation from the client the setter delegate will be called. If your
+// application also generates or updates data periodically, it can push those updates to the server via call to
+// `ggkNofifyUpdatedCharacteristic()` or `ggkNofifyUpdatedDescriptor()`.
+//
+// >>
+// >>> UNDERSTANDING THE UNDERLYING FRAMEWORKS
+// >>
+//
+// The server description below attempts to provide a GATT-based interface in terms of GATT services, characteristics and
+// descriptors. Consider the following sample:
+//
+// .gattServiceBegin("text", "00000001-1E3C-FAD4-74E2-97A033F1BFAA")
+// .gattCharacteristicBegin("string", "00000002-1E3C-FAD4-74E2-97A033F1BFAA", {"read", "write", "notify"})
+//
+// .onReadValue(CHARACTERISTIC_METHOD_CALLBACK_LAMBDA
+// {
+// // Abbreviated for simplicity
+// self.methodReturnValue(pInvocation, myTextString, true);
+// })
+//
+// .onWriteValue(CHARACTERISTIC_METHOD_CALLBACK_LAMBDA
+// {
+// // Abbreviated for simplicity
+// myTextString = ...
+// })
+//
+// .gattDescriptorBegin("description", "2901", {"read"})
+// .onReadValue(DESCRIPTOR_METHOD_CALLBACK_LAMBDA
+// {
+// self.methodReturnValue(pInvocation, "Returns a test string", true);
+// })
+//
+// .gattDescriptorEnd()
+// .gattCharacteristicEnd()
+// .gattServiceEnd()
+//
+// The first thing you may notice abpout the sample is that all of the lines begin with a dot. This is because we're chaining
+// methods together. Each method returns the appropriate type to provide context. For example, The `gattServiceBegin` method returns
+// a reference to a `GattService` object which provides the proper context to create a characteristic within that service.
+// Similarly, the `gattCharacteristicBegin` method returns a reference to a `GattCharacteristic` object which provides the proper
+// context for responding to requests to read the characterisic value or add descriptors to the characteristic.
+//
+// For every `*Begin` method, there is a corresponding `*End` method, which returns us to the previous context. Indentation helps us
+// keep track of where we are.
+//
+// Also note the use of the lambda macros, `CHARACTERISTIC_METHOD_CALLBACK_LAMBDA` and `DESCRIPTOR_METHOD_CALLBACK_LAMBDA`. These
+// macros simplify the process of including our implementation directly in the description.
+//
+// The first parameter to each of the `*Begin` methods is a path node name. As we build our hierarchy, we give each node a name,
+// which gets appended to it's parent's node (which in turns gets appended to its parent's node, etc.) If our root path was
+// "/com/gobbledegook", then our service would have the path "/com/gobbledegook/text" and the characteristic would have the path
+// "/com/gobbledegook/text/string", and the descriptor would have the path "/com/gobbledegook/text/string/description". These paths
+// are important as they act like an addressing mechanism similar to paths on a filesystem or in a URL.
+//
+// The second parameter to each of the `*Begin` methods is a UUID as defined by the Bluetooth standard. These UUIDs effectively
+// refer to an interface. You will see two different kinds of UUIDs: a short UUID ("2901") and a long UUID
+// ("00000002-1E3C-FAD4-74E2-97A033F1BFAA").
+//
+// For more information on UUDSs, see GattUuid.cpp.
+//
+// In the example above, our non-standard UUIDs ("00000001-1E3C-FAD4-74E2-97A033F1BFAA") are something we generate ourselves. In the
+// case above, we have created a custom service that simply stores a mutable text string. When the client enumerates our services
+// they'll see this UUID and, assuming we've documented our interface behind this UUID for client authors, they can use our service
+// to read and write a text string maintained on our server.
+//
+// The third parameter (which only applies to dharacteristics and descriptors) are a set of flags. You will find the current set of
+// flags for characteristics and descriptors in the "BlueZ D-Bus GATT API description" at:
+//
+// https://git.kernel.org/pub/scm/bluetooth/bluez.git/plain/doc/gatt-api.txt
+//
+// In addition to these structural methods, there are a small handful of helper methods for performing common operations. These
+// helper methods are available within a method (such as `onReadValue`) through the use of a `self` reference. The `self` reference
+// refers to the object at which the method is invoked (either a `GattCharacteristic` object or a `GattDescriptor` object.)
+//
+// methodReturnValue and methodReturnVariant
+// These methods provide a means for returning values from Characteristics and Descriptors. The `-Value` form accept a set
+// of common types (int, string, etc.) If you need to provide a custom return type, you can do so by building your own
+// GVariant (which is a GLib construct) and using the `-Variant` form of the method.
+//
+// sendChangeNotificationValue and sendChangeNotificationVariant
+// These methods provide a means for notifying changes for Characteristics. The `-Value` form accept a set of common types
+// (int, string, etc.) If you need to notify a custom return type, you can do so by building your own GVariant (which is a
+// GLib construct) and using the `-Variant` form of the method.
+//
+// For information about GVariants (what they are and how to work with them), see the GLib documentation at:
+//
+// https://www.freedesktop.org/software/gstreamer-sdk/data/docs/latest/glib/glib-GVariantType.html

+ // D-Bus Object Manager that solely manages the objects of that service. Hence, the standard DBus.ObjectManager interface

+ // The object types and method names used in the code below may look unfamiliar compared to what you're used to seeing in the
+ // Server desecription. That's because the server description uses higher level types that define a more GATT-oriented framework
+ // to build your GATT services. That higher level functionality was built using a set of lower-level D-Bus-oriented framework,

+// A TIckEvent is an event that is triggered on a regular timer interval.

+// >>
+// >>> DISCUSSION
+// >>
+//
+// Tick events are used within the Server's description in Server.cpp. As you might expect, they are useful for updating data on a
+// regular basis or performing other periodic tasks. One example usage might be checking the battery level every 60 seconds and if
+// it has changed since the last update, send out a notification to subscribers.
+//
+// The frequency at which events fire is dependent upon two values: the driving timer's tick frequency multiplied by the tick
+// freuency of the TickEvent itself.
+//
+// The tick event's frequency is set when a tick event is added via the `onEvent()` method to the server description.
+//
+// The driving timer's frequency is a one-second-resolution low-frequency timer with a default of one second. To modify this, see
+// `kPeriodicTimerFrequencySeconds` at the top of Init.cpp. Note that the periodic timer (which drives tick events) is intentionally
+// a low-frequency timer. Higher frequency timers would lend themselves to using more battery on both, the server and client.
+//
+// When using a TickEvent, be careful not to demand too much of your client. Notifiations that are too frequent may place undue
+// stress on their battery to receive and process the updates.

+//
+// >>
+// >>> INSIDE THIS FILE
+// >>
+//
+// This is an example single-file stand-alone application that runs a Gobbledegook server.
+//
+// >>
+// >>> DISCUSSION
+// >>
+//
+// Very little is required ("MUST") by a stand-alone application to instantiate a valid Gobbledegook server. There are also some
+// things that are reocommended ("SHOULD").
+//
+// * A stand-alone application MUST:
+//
+// * Start the server via a call to `ggkStart()`.
+//
+// Once started the server will run on its own thread.
+//
+// Two of the parameters to `ggkStart()` are delegates responsible for providing data accessors for the server, a
+// `GGKServerDataGetter` delegate and a 'GGKServerDataSetter' delegate. The getter method simply receives a string name (for
+// example, "battery/level") and returns a void pointer to that data (for example: `(void *)&batteryLevel`). The setter does
+// the same only in reverse.
+//
+// While the server is running, you will likely need to update the data being served. This is done by calling
+// `ggkNofifyUpdatedCharacteristic()` or `ggkNofifyUpdatedDescriptor()` with the full path to the characteristic or delegate
+// whose data has been updated. This will trigger your server's `onUpdatedValue()` method, which can perform whatever
+// actions are needed such as sending out a change notification (or in BlueZ parlance, a "PropertiesChanged" signal.)
+//
+// * A stand-alone application SHOULD:
+//
+// * Shutdown the server before termination
+//
+// Triggering the server to begin shutting down is done via a call to `ggkTriggerShutdown()`. This is a non-blocking method
+// that begins the asynchronous shutdown process.
+//
+// Before your application terminates, it should wait for the server to be completely stopped. This is done via a call to
+// `ggkWait()`. If the server has not yet reached the `EStopped` state when `ggkWait()` is called, it will block until the
+// server has done so.
+//
+// To avoid the blocking behavior of `ggkWait()`, ensure that the server has stopped before calling it. This can be done
+// by ensuring `ggkGetServerRunState() == EStopped`. Even if the server has stopped, it is recommended to call `ggkWait()`
+// to ensure the server has cleaned up all threads and other internals.
+//
+// If you want to keep things simple, there is a method `ggkShutdownAndWait()` which will trigger the shutdown and then
+// block until the server has stopped.
+//
+// * Implement signal handling to provide a clean shut-down
+//
+// This is done by calling `ggkTriggerShutdown()` from any signal received that can terminate your application. For an
+// example of this, search for all occurrences of the string "signalHandler" in the code below.
+//
+// * Register a custom logging mechanism with the server
+//
+// This is done by calling each of the log registeration methods:
+//
+// `ggkLogRegisterDebug()`
+// `ggkLogRegisterInfo()`
+// `ggkLogRegisterStatus()`
+// `ggkLogRegisterWarn()`
+// `ggkLogRegisterError()`
+// `ggkLogRegisterFatal()`
+// `ggkLogRegisterAlways()`
+// `ggkLogRegisterTrace()`
+//
+// Each registration method manages a different log level. For a full description of these levels, see the header comment
+// in Logger.cpp.
+//
+// The code below includes a simple logging mechanism that logs to stdout and filters logs based on a few command-line
+// options to specify the level of verbosity.

+// >>> Building with GOBBLEDEGOOK
+// >>
+//
+// The Gobbledegook distribution includes this file as part of the Gobbledegook files with everything compiling to a single, stand-
+// alone binary. It is built this way because Gobbledegook is not intended to be a generic library. You will need to make your
+// custom modifications to it. Don't worry, a lot of work went into Gobbledegook to make it almost trivial to customize
+// (see Server.cpp).
+//
+// If it is important to you or your build process that Gobbledegook exist as a library, you are welcome to do so. Just configure
+// your build process to build the Gobbledegook files (minus this file) as a library and link against that instead. All that is
+// required by applications linking to a Gobbledegook library is to include `include/Gobbledegook.h`.
