359
360	=item $term = new urxvt [arg...]
361
362	Creates a new terminal, very similar as if you had started it with
363	C<system $binfile, arg...>. Croaks (and probably outputs an error message)
364	if the new instance couldn't be created. Returns C<undef> if the new
365	instance didn't initialise perl, and the terminal object otherwise. The
366	C<init> and C<start> hooks will be called during the call.
367
368	=item urxvt::fatal $errormessage
369
370	Fatally aborts execution with the given error message. Avoid at all
371	costs! The only time this is acceptable is when the terminal process
372	starts up.
373
374	=item urxvt::warn $string
375
376	Calls C<rxvt_warn> with the given string which should not include a
377	newline. The module also overwrites the C<warn> builtin with a function
378	that calls this function.
379
380	Using this function has the advantage that its output ends up in the
381	correct place, e.g. on stderr of the connecting urxvtc client.
382
383	=item $is_safe = urxvt::safe
384
385	Returns true when it is safe to do potentially unsafe things, such as
386	evaluating perl code specified by the user. This is true when urxvt was
387	started setuid or setgid.

408	The following "macros" deal with changes in rendition sets. You should

414
415	=item $rend = urxvt::DEFAULT_RSTYLE
416
417	Returns the default rendition, as used when the terminal is starting up or
418	being reset. Useful as a base to start when creating renditions.
419
420	=item $rend = urxvt::OVERLAY_RSTYLE

422	Return the rendition mask used for overlays by default.
423
424	=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
425
426	Return the bit that enabled bold, italic, blink, reverse-video and
427	underline, respectively. To enable such a style, just logically OR it into
428	the bitset.

441	specified one.
442
443	=item $value = urxvt::GET_CUSTOM ($rend)
444
445	Return the "custom" value: Every rendition has 5 bits for use by
446	extensions. They can be set and changed as you like and are initially
447	zero.
448
449	=item $rend = urxvt::SET_CUSTOM ($rend, $new_value)
