+=head1 SYNOPSIS
+
+  use Data::MultiValued::Ranges;
+
+  my $obj = Data::MultiValued::Ranges->new();
+  $obj->set({
+    from => 10,
+    to => 20,
+    value => 'foo',
+  });
+  say $obj->get({at => 15}); # prints 'foo'
+  say $obj->get({at => 35}); # dies
+
+=head1 METHODS
+
+=head2 C<set>
+
+  $obj->set({ from => $min, to => $max, value => $the_value });
+
+Stores the given value for the given range. Does not throw exceptions.
+
+The range is defined as C<< Num $x : $min <= $x < $max >>.
+
+If the given range intersects existing ranges, these are spliced to
+avoid overlaps. In other words:
+
+  $obj->set({
+    from => 10,
+    to => 20,
+    value => 'foo',
+  });
+  $obj->set({
+    from => 15,
+    to => 25,
+    value => 'bar',
+  });
+  say $obj->get({at => 12}); # prints 'foo'
+  say $obj->get({at => 15}); # prints 'bar'
+  say $obj->get({at => 25}); # dies
+
+No cloning is done: if you pass in a reference, the reference is
+just stored.
+
+=head2 C<get>
+
+  my $value = $obj->get({ at => $point });
+
+Retrieves the value for the given point. Throws a
+L<Data::MultiValued::Exceptions::RangeNotFound> exception if no ranges
+exist in this object that include the point (remember that a range
+does not include its C<to> point).
+
+No cloning is done: if a reference was stored, you get it back
+untouched.
+
+=head2 C<clear>
+
+  $obj->clear({ from => $min, to => $max });
+
+Deletes all values for the given range. Does not throw exceptions.
+
+If the given range intersects existing ranges, these are spliced. In
+other words:
+
+  $obj->set({
+    from => 10,
+    to => 20,
+    value => 'foo',
+  });
+  $obj->clear({
+    from => 15,
+    to => 25,
+  });
+  say $obj->get({at => 12}); # prints 'foo'
+  say $obj->get({at => 15}); # dies
