+Uses per-line display filtering (C<on_line_update>) to underline urls and
+make them clickable. When middle-clicked, the program specified in the
+resource C<urlLauncher> (default C<x-www-browser>) will be started.
 =item block-graphics-to-ascii
 A not very useful example of filtering all text output to the terminal,
 by replacing all line-drawing characters (U+2500 .. U+259F) by a

 =item $text
 Rxvt-unicodes special way of encoding text, where one "unicode" character

+always represents one screen cell. See L<ROW_t> for a discussion of this format.
 =item $string
 A perl text string, with an emphasis on I<text>. It can store all unicode
 characters and is to be distinguished with text encoded in a specific
 subwindow.

-The rxvt-unicode library directory, where, among other things, the perl

-The resource class and name rxvt-unicode uses to look up X resources.

-=over 4
-=item $term = new urxvt [arg...]
-Creates a new terminal, very similar as if you had started it with
-C<system $binfile, arg...>. Croaks (and probably outputs an error message)
-if the new instance couldn't be created.  Returns C<undef> if the new
-instance didn't initialise perl, and the terminal object otherwise. The
-C<init> and C<start> hooks will be called during the call.
-=item urxvt::fatal $errormessage
-Fatally aborts execution with the given error message. Avoid at all
-costs! The only time this is acceptable is when the terminal process
-starts up.
-=item urxvt::warn $string
-Calls C<rxvt_warn> with the given string which should not include a
-newline. The module also overwrites the C<warn> builtin with a function
-that calls this function.
-Using this function has the advantage that its output ends up in the
-correct place, e.g. on stderr of the connecting urxvtc client.
-=item $is_safe = urxvt::safe
-Returns true when it is safe to do potentially unsafe things, such as
-evaluating perl code specified by the user. This is true when urxvt was
-started setuid or setgid.
-=item $time = urxvt::NOW
-Returns the "current time" (as per the event loop).

-=item urxvt::ShiftMask, LockMask, ControlMask, Mod1Mask, Mod2Mask,

-=head2 RENDITION
-Rendition bitsets contain information about colour, font, font styles and
-similar information for each screen cell.
-The following "macros" deal with changes in rendition sets. You should
-never just create a bitset, you should always modify an existing one,
-as they contain important information required for correct operation of
-rxvt-unicode.
-=over 4
-=item $rend = urxvt::DEFAULT_RSTYLE
-Returns the default rendition, as used when the terminal is starting up or
-being reset. Useful as a base to start when creating renditions.
-=item $rend = urxvt::OVERLAY_RSTYLE
-Return the rendition mask used for overlays by default.
-=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
-Return the bit that enabled bold, italic, blink, reverse-video and
-underline, respectively. To enable such a style, just logically OR it into
-the bitset.
-=item $foreground = urxvt::GET_BASEFG $rend
-=item $background = urxvt::GET_BASEBG $rend
-Return the foreground/background colour index, respectively.
-=item $rend = urxvt::SET_FGCOLOR $rend, $new_colour
-=item $rend = urxvt::SET_BGCOLOR $rend, $new_colour
-Replace the foreground/background colour in the rendition mask with the
-specified one.

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