		117	=head2 META comments
		118
		119	Rxvt-unicode recognizes special meta comments in extensions that define
		120	different types of metadata. These comments are scanned whenever a
		121	terminal is created and are typically used to autoload extensions when
		122	their resources or command line parameters are used.
		123
		124	Currently, it recognises these comments below. Individual components are
		125	separated by colons (C<:>), and should not contain colons themselves -
		126	there is also currently no escaping mechanism provided for this.
		127
		128	=over
		129
		130	=item #:META:RESOURCE:name:type:desc
		131
		132	The RESOURCE comment defines a resource used by the extension, where
		133	C<name> is the resource name, C<type> is the resource type, C<boolean>
		134	or C<string>, and C<desc> is the resource description.
		135
		136	The extension will be autoloaded when this resource is specified or used
		137	as a command line parameter.
		138
		139	Example: matcher provides the C<matcher.launcher> resource by having this
		140	comment:
		141
		142	#:META:RESOURCE:%.launcher:string:default launcher command
		143
		144	Example: load this extension when the C<-tr> command line option or
		145	resource name is used.
		146
		147	#:META:RESOURCE:tr:boolean:set root pixmap as background
		148
		149	=item #:META:OSC:number:desc
		150
		151	The OSC comment specifies an OSC sequence, where C<number> is the
		152	numerical OSC code and C<desc> is a short description that is currently
		153	unused.
		154
		155	This will cause the extension to be autoloaded when the OSC sequence is
		156	used for the first time.
		157
		158	Note that autoloading carries some extra responsibilities with it:
		159	although the terminal cannot really protect itself against malicious
		160	sources of command sequences, therefore relying on the programs running
		161	I<inside> to sanitize data that they output, it is very common for
		162	programs to emit command sequences from untrusted sources.
		163
		164	While this means that extensions should, as a defense-in-depth mechanism,
		165	always consider whether OSC sequences are safe, autoloading automatically
		166	exposes any autoloaded extension in all terminal windows, so extra care
		167	should be taken.
		168
		169	Example: the background extension registers OSC C<20> like this:
		170
		171	#:META:OSC:20:change/query background image
		172
		173	=item #:META:OSC_PERL:prefix:desc
		174
		175	The same as the OSC comment, but for the Perl OSC sequence (C<777>). The
		176	C<prefix> should be unique among extensions, of course, which is most
		177	easily arranged by using the extension name, although this is not
		178	required.
		179
		180	Example: the overlay-osc extension registers its Perl OSC like this:
		181
		182	#:META:OSC_PERL:overlay:man overlay-osc
