357	=item $term = new urxvt [arg...]
358
359	Creates a new terminal, very similar as if you had started it with
360	C<system $binfile, arg...>. Croaks (and probably outputs an error message)
361	if the new instance couldn't be created. Returns C<undef> if the new
362	instance didn't initialise perl, and the terminal object otherwise. The
363	C<init> and C<start> hooks will be called during the call.
364
365	=item urxvt::fatal $errormessage
366
367	Fatally aborts execution with the given error message. Avoid at all
368	costs! The only time this is acceptable is when the terminal process
369	starts up.
370
371	=item urxvt::warn $string
372
373	Calls C<rxvt_warn> with the given string which should not include a
374	newline. The module also overwrites the C<warn> builtin with a function
375	that calls this function.
376
377	Using this function has the advantage that its output ends up in the
378	correct place, e.g. on stderr of the connecting urxvtc client.
379
380	=item $is_safe = urxvt::safe
381
382	Returns true when it is safe to do potentially unsafe things, such as

384	started setuid or setgid.

402	Rendition bitsets contain information about colour, font, font styles and
403	similar information for each screen cell.
404
405	The following "macros" deal with changes in rendition sets. You should

407	as they contain important information required for correct operation of
408	rxvt-unicode.

415	being reset. Useful as a base to start when creating renditions.
416

419	Return the rendition mask used for overlays by default.
420

422
423	Return the bit that enabled bold, italic, blink, reverse-video and
424	underline, respectively. To enable such a style, just logically OR it into
425	the bitset.

441
442	Return the "custom" value: Every rendition has 5 bits for use by

444	zero.
