		101
		102	=head2 Extension Objects
		103
		104	Every perl extension is a perl class. A separate perl object is created
		105	for each terminal, and each terminal has its own set of extension objects,
		106	which are passed as the first parameter to hooks. So extensions can use
		107	their C<$self> object without having to think about clashes with other
		108	extensions or other terminals, with the exception of methods and members
		109	that begin with an underscore character C<_>: these are reserved for
		110	internal use.
		111
		112	Although it isn't a C<urxvt::term> object, you can call all methods of the
		113	C<urxvt::term> class on this object.
		114
		115	Additional methods only supported for extension objects are described in
		116	the C<urxvt::extension> section below.
		117
		118	=head2 META comments
		119
		120	Rxvt-unicode recognizes special meta comments in extensions that define
		121	different types of metadata.
		122
		123	Currently, it recxognises only one such comment:
		124
		125	=over 4
		126
		127	=item #:META:RESOURCE:name:type:desc
		128
		129	The RESOURCE comment defines a resource used by the extension, where
		130	C<name> is the resource name, C<type> is the resource type, C<boolean>
		131	or C<string>, and C<desc> is the resource description.

		1317	resource with that pattern exists.
		1318
		1319	Extensions that define extra resources also need to call this method
		1320	to access their values.
		1321
		1322	If the method is called on an extension object (basically, from an
		1323	extension), then the special prefix C<%.> will be replaced by the name of
		1324	the extension and a dot, and the lone string C<%> will be replaced by the
		1325	extension name itself. This makes it possible to code extensions so you
		1326	can rename them and get a new set of resources without having to change
		1327	the actual code.
		1328
		1329	This method should only be called during the C<on_start> hook, as there is
		1330	only one resource database per display, and later invocations might return
		1331	the wrong resources.

		1354	To add default bindings for an extension, the extension should call C<<

		1356	in the C<init> hook allows users the override or remove the the binding
		1357	again.

		1359	Example: the C<searchable-scrollback> by default binds itself
