		99	Argument names also often indicate the type of a parameter. Here are
		100	some hints on what they mean:
		101
		102	$text
		103	Rxvt-unicodes special way of encoding text, where one "unicode"
		104	character always represents one screen cell. See ROW_t for a
		105	discussion of this format.
		106
		107	$string
		108	A perl text string, with an emphasis on text. It can store all
		109	unicode characters and is to be distinguished with text encoded in a
		110	specific encoding (often locale-specific) and binary data.
		111
		112	$octets
		113	Either binary data or - more common - a text string encoded in a
		114	locale-specific way.
		115
		116	Extension Objects
		117	Very perl extension is a perl class. A separate perl object is created
		118	for each terminal and each extension and passed as the first parameter
		119	to hooks. So extensions can use their $self object without having to
		120	think about other extensions, with the exception of methods and members
		121	that begin with an underscore character "_": these are reserved for
		122	internal use.
		123
		124	Although it isn't a "urxvt::term" object, you can call all methods of
		125	the "urxvt::term" class on this object.
		126
		127	It has the following methods and data members:
		128
		129	$urxvt_term = $self->{term}
		130	Returns the "urxvt::term" object associated with this instance of
		131	the extension. This member must not be changed in any way.
		132
		133	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		134	Dynamically enable the given hooks (named without the "on_" prefix)
		135	for this extension, replacing any previous hook. This is useful when
		136	you want to overwrite time-critical hooks only temporarily.
		137
		138	$self->disable ($hook_name[, $hook_name..])
		139	Dynamically disable the given hooks.

128	output.	212	operating system command) is processed. Cursor position and other
		213	state information is up-to-date when this happens. For
		214	interoperability, the string should start with the extension name
		215	and a colon, to distinguish it from commands for other extensions,
		216	and this might be enforced in the future.
		217
		218	Be careful not ever to trust (in a security sense) the data you
		219	receive, as its source can not easily be controleld (e-mail content,
		220	messages from other users on the same system etc.).
		221
		222	on_add_lines $term, $string
		223	Called whenever text is about to be output, with the text as
		224	argument. You can filter/change and output the text yourself by
		225	returning a true value and calling "$term->scr_add_lines" yourself.
		226	Please note that this might be very slow, however, as your hook is
		227	called for all text being output.
		228
		229	on_tt_write $term, $octets
		230	Called whenever some data is written to the tty/pty and can be used
		231	to suppress or filter tty input.
		232
		233	on_line_update $term, $row
		234	Called whenever a line was updated or changed. Can be used to filter
		235	screen output (e.g. underline urls or other useless stuff). Only
		236	lines that are being shown will be filtered, and, due to performance
		237	reasons, not always immediately.
		238
		239	The row number is always the topmost row of the line if the line
		240	spans multiple rows.
		241
		242	Please note that, if you change the line, then the hook might get
		243	called later with the already-modified line (e.g. if unrelated parts
		244	change), so you cannot just toggle rendition bits, but only set
		245	them.

		264
		265	on_focus_out $term
		266	Called wheneever the window loses keyboard focus, before

		279
		280	The event is a hash with most values as named by Xlib (see the

		333	Various constants for use in X calls and event processing.
		334
		335	RENDITION
		336	Rendition bitsets contain information about colour, font, font styles
		337	and similar information for each screen cell.
		338
		339	The following "macros" deal with changes in rendition sets. You should
		340	never just create a bitset, you should always modify an existing one, as
		341	they contain important information required for correct operation of
		342	rxvt-unicode.
		343
		344	$rend = urxvt::DEFAULT_RSTYLE
		345	Returns the default rendition, as used when the terminal is starting
		346	up or being reset. Useful as a base to start when creating
		347	renditions.
		348
		349	$rend = urxvt::OVERLAY_RSTYLE
		350	Return the rendition mask used for overlays by default.
		351
		352	$rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
		353	Return the bit that enabled bold, italic, blink, reverse-video and
		354	underline, respectively. To enable such a style, just logically OR
		355	it into the bitset.
		356
		357	$foreground = urxvt::GET_BASEFG $rend
		358	$background = urxvt::GET_BASEBG $rend
		359	Return the foreground/background colour index, respectively.
		360
		361	$rend = urxvt::SET_FGCOLOR $rend, $new_colour
		362	$rend = urxvt::SET_BGCOLOR $rend, $new_colour

		364	the specified one.
		365
		366	$value = urxvt::GET_CUSTOM $rend
		367	Return the "custom" value: Every rendition has 5 bits for use by
		368	extensions. They can be set and changed as you like and are
		369	initially zero.
		370
		371	$rend = urxvt::SET_CUSTOM $rend, $new_value
		372	Change the custom value.
		373
		374	The "urxvt::anyevent" Class
		375	The sole purpose of this class is to deliver an interface to the
		376	"AnyEvent" module - any module using it will work inside urxvt without
		377	further programming. The only exception is that you cannot wait on
		378	condition variables, but non-blocking condvar use is ok. What this means
		379	is that you cannot use blocking APIs, but the non-blocking variant
		380	should work.

161	The "urxvt::term" Class	382	The "urxvt::term" Class
		383	$term = new urxvt::term $envhashref, $rxvtname, [arg...]
		384	Creates a new terminal, very similar as if you had started it with
		385	system "$rxvtname, arg...". $envhashref must be a reference to a
		386	%ENV-like hash which defines the environment of the new terminal.
		387
		388	Croaks (and probably outputs an error message) if the new instance
		389	couldn't be created. Returns "undef" if the new instance didn't
		390	initialise perl, and the terminal object otherwise. The "init" and
		391	"start" hooks will be called during this call.
		392
		393	$term->destroy
		394	Destroy the terminal object (close the window, free resources etc.).
		395	Please note that rxvt will not exit as long as any event watchers
		396	(timers, io watchers) are still active.
		397
		398	$isset = $term->option ($optval[, $set])
		399	Returns true if the option specified by $optval is enabled, and
		400	optionally change it. All option values are stored by name in the
		401	hash %urxvt::OPTION. Options not enabled in this binary are not in
		402	the hash.
