+    rxvt-unicode, version 7.9, is a colour vt102 terminal emulator intended
     as an *xterm*(1) replacement for users who do not require features such

     result, rxvt-unicode uses much less swap space -- a significant
     advantage on a machine serving many X sessions.
     world. Being a terminal emulator, however, some things are very
     difficult, especially cursive scripts such as arabic, vertically written
     scripts like mongolian or scripts requiring extremely complex combining
     rules, like tibetan or devenagari. Don't expect pretty output when using
     these scripts. Most other scripts, latin, cyrillic, kanji, thai etc.

+    should work fine, though. A somewhat difficult case are right-to-left
     scripts, such as hebrew: rxvt-unicode adopts the view that bidirectional
     algorithms belong into the application, not the terminal emulator (too
     many things -- such as cursor-movement while editing -- break
     otherwise), but that might change.

     terminal emulator. In fact, the reason rxvt-unicode was born was solely
     because the author couldn't get "mlterm" to use one font for latin1 and
     another for japanese.
     Therefore another design rationale was the use of multiple fonts to
     display characters: The idea of a single unicode font which many other

     improvements.

     client/daemon pair that lets you open any number of terminal windows
     from within a single process, which makes startup time very fast and
     drastically reduces memory usage. See rxvtd(1) (daemon) and rxvtc(1)

     -tint *colour*
         Tint the transparent background pixmap with the given colour when

         non-tiled backgrounds, currently. See also the -sh option that can

         other fonts might be smaller, but not (in general) larger. A

         prefix it with "x:". To specify an XFT-font, you need to prefix it
         with "xft:", e.g.:
            rxvt -fn "xft:Bitstream Vera Sans Mono:pixelsize=15"
            rxvt -fn "9x15bold,xft:Bitstream Vera Sans Mono"
     -keysym.*sym* *string*

         which enables applications to easily embed a terminal.
         Right now, rxvt will first unmap/map the specified window, so it
         shouldn't be a top-level window. rxvt will also reconfigure it quite
         a bit, so don't expect it to keep some specific state. It's best to

         It might be useful to know that rxvt will not close file descriptors
         passed to it (except for stdin/out/err, of course), so you can use
         file descriptors to communicate with the programs within the

         used or not.
         Here is a short Gtk2-perl snippet that illustrates how this option
         can be used (a longer example is in doc/embed):
               system "rxvt -embed $xid &";
            });

         useful if you want to drive rxvt as a generic terminal emulator
         without having to run a program within it.
         If this switch is given, rxvt will not create any utmp/wtmp entries
         and will not tinker with pty/tty permissions - you have to do that
     settings. The following resources are supported (you might want to check
     the rxvtperl(3) manpage for additional settings by perl extensions not

     It is also possible to specify the colour values of foreground,
     background, cursorColor, cursorColor2, colorBD, colorUL as a number
     0-15, as a convenient shorthand to reference the colour name of
     color0-color15.
+    In addition to the colours defined above, rxvt offers an additional 72
+    colours. The first 64 of those (with indices 16 to 79) consist of a
+    4*4*4 RGB colour cube (i.e. *index = r * 16 + g * 4 + b + 16*), followed
+    by 8 additional shades of gray (with indices 80 to 87).
+    Together, all those colours implement the 88 colour xterm colours. Only
+    the first 16 can be changed using resources currently, the rest can only
+    be changed via command sequences ("escape codes").
     Note that -rv ("reverseVideo: True") simulates reverse video by always
     swapping the foreground/background colours. This is in contrast to
     *xterm*(1) where the colours are only swapped if they have not otherwise
     been specified. For example,
     rxvt -fg Black -bg White -rv
         would yield White on Black, while on *xterm*(1) it would yield Black
         on White.
+  ALPHA CHANNEL SUPPORT
+    If Xft support has been compiled in and as long as Xft/Xrender/X don't
+    get their act together, rxvt-unicode will support
+    "rgba:rrrr/gggg/bbbb/aaaa" (recommended, but MUST have 4
+    digits/component) colour specifications, in addition to the ones
+    provided by X, where the additional A component specifies opacity
+    (alpha) values. The minimum value of 0 is completely transparent). You
+    can also prefix any color with "[a]", where "a" is on to four hex digits
+    specifiying the opacity value.
+    You probably need to specify "-depth 32", too, and have the luck that
+    your X-server uses ARGB pixel layout, as X is far from just supporting
+    ARGB visuals out of the box, and rxvt-unicode just fudges around.
+    For example, the following selects an almost completely transparent red
+    background, and an almost opaque pink foreground:
+       rxvt -depth 32 -bg rgba:0000/0000/0000/2222 -fg "[e]pink"
+    *Please note that transparency of any kind if completely unsupported by
+    the author. Don't bug him with installation questions!*
