		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 comments in extensions that define
		121	different types of metadata:
		122
		123	=over 4
		124
		125	=item #:META:RESOURCE:name:type:desc
		126
		127	The RESOURCE comment defines a resource used by the extension, where
		128	C<name> is the resource name, C<type> is the resource type, C<boolean>
		129	or C<string>, and C<desc> is the resource description.
		130
		131	=item #:META:BINDING:sym:action
		132
		133	The BINDING comment defines a default binding for an action provided
		134	by the extension, where C<sym> is the key combination that triggers
		135	the action, whose format is defined in the description of the
		136	B<keysym> resource in the urxvt(1) manpage, and C<action> is the name
		137	of the action method.
