+========
+History
+========
+
+This program, BiCon, has a very entangled history.
+That being said, here is a try on explaining it.
+
+Prologue
+--------
+
+The program is the last in a series on programs to make the
+console support bidirectionality. This has been needed in the
+Arabic, Persian and Hebrew languages among others.
+
+Acon
+----
+Written by Ahmed Abdel-Hamid Mohamed, this was the first program
+that enjoyed relatively wide support, as it was distributed in
+Mandrake.
+
+Akka
+----
+The second effort has gone into improving the original acon code
+and giving it vast additional abilities, this was the Akka
+project, in Arabeyes. The Akka project is still there, if
+somebody wants to look at it. Key contributors are Chahine
+Hamila, Mohamed Elzubeir and Samy Al Bahra. It reached the
+version 1.0 beta, but the code is becoming too complicated for
+further enhancements.  Additional information is found in the
+project site, at Arabeyes.
+
+Farsi
+-----
+Taking place more or less parallel to the Akka development,
+Behdad Esfahbod - widely known for his work on FriBidi - wrote
+"farsi", as a tool doing the same job as Akka, more Persian
+oriented.  He adopted the basic joining code from Roozbeh
+Pournader, and borrowed some from script(1), mixed and matched
+with FriBidi and Voila!  The code from script(1) proved to be the
+major stopper for its distribution. More of the story can be
+found in HISTORY.farsi, in this package.
+
+At last: BiCon
+--------------
+The next step in Arabeyes was to base the code on the old farsi
+code. After cleaning up the problematic-licensed code and
+enhancing Arabic support besides Persian, _BiCon_ was there.
+
+Here is the old ChangeLog:
+
+
+2004-January  Behdad Esfahbod <bicon@behdad.org>
+	* *: Well, code is handed to Arabeyes people.  Decided to
+	change the name to "BiCon".  I'm not going to be the
+	maintainer anymore (hopefully).  Already imported to
+	Arabeyes CVS.  These nice people have removed the code
+	borrowed from "script" and replaced with code from Python
+	sources.  We are still to make changes to fit the new
+	system.  Thanks guys.
+
+==========================================================================
+
+2002-06-13  Behdad Esfahbod <farsi@behdad.org>
+	* */*.[ch]: Major changes.  Support many options now, among them is
+	the option to output logical text, not visual.
+
+2002-06-12  Behdad Esfahbod <farsi@behdad.org>
+	* keymap/isiri2901.kmap.gz: Proposed key positions for bidi marks
+	added.
+
+2001-12-14  Behdad Esfahbod <behdad@bamdad.org>
+	* farsi: Makes the shells current directory to be the same as when
+	user runs the script.
+
+2001-12-05  Behdad Esfahbod <behdad@bamdad.org>
+	* fcon/fcon.c: Now accepts parameters to run instead of default /bin/sh.
+	* bin/farsi: Pass parameteres to fcon.
+	* bin/farsidict: A small script for dictionary lookup, using farsi.
+
+2001-10-13  Behdad Esfahbod <behdad@bamdad.org>
+	* */Makefile: Small changes.
+
+2001-10-04  Behdad Esfahbod <behdad@bamdad.org>
+	* fconsole/Makefile: Set target clean to remove fconsole-config too.
+
+2001-9-22   Behdad Esfahbod <behdad@bamdad.org>
+	* First released under farsidev mailing list.

+BiCon: a Bidirectional Console
+
+BiCon can be used under Linux console, or terminal emulators with
+basic Unicode rendering (UTF-8).
+
+Run "bicon" to get a console supporting Arabic or Persian according
+to LANG or specify the country on the command line, for instance:
+  bicon ir # for Persian (Iran)
+
+Keymaps and fonts for Arabic and Persian are included. 
+
+Use alt+shift to switch keyboard layouts in a graphical environment.
+To know more:
+
+  "man bicon"
+and
+  "man bicon.bin"
+
+See also /usr/doc/bicon-<VERSION>/README.Slackware for BiCon's usage.

+BiCon is maintained by Behdad Esfahbod.

+Additional information about BiCon's behavior
+=============================================
+
+BiCon behaves differently if called as "bicon" or "bicon.bin", and also
+started from the console (or a tty) versus in a graphical environment.
+
+BiCon ships two keymaps: arabic.map.gz and ir.map.gz and some console
+fonts, mainly bicon-8x16-512.psfu.gz.
+
+It can be started as "bicon" or "bicon.bin"
+
+If started as "bicon" it sets the keymap or keyboard layout in a way that
+depends whether the "bicon" command is given or not an argument.
+
+1) If started as "bicon" from the console.
+
+If a two characters country code is given as argument it is considered
+to choose the keymap, else the country (or "territory" to be accurate)
+part of LANG is used.
+_ If the country (converted to lowercase letters) is found in this list:
+  ae dz eg iq jo ko kw lb ly ma om qa sa sd sy tn ye
+  then the keymap "arabic" is chosen.
+_ If the country is "IR" or "ir" then the keymap "ir" is chosen.
+
+The font bicon-8x16-512 is always used with its Unicode map.
+
+IMPORTANT. You won't be able to use the "setfont" command after having
+started bicon as a regular user. You will have to tentatively become root
+with "su" to change the font if you want.
+
+2) If started as "bicon" from an X terminal.
+
+You will need to use an UTF-8 able or enabled terminal.
+
+A switchable keyboard layout (us + the language that correspond to the
+country set by the user or found in LANG) is set.
+
+IMPORTANT:
+_ BiCon doesn't set the font. You'll have to do that yourself. Be careful
+  to use a font including the needed glyphs.
+_ BiCon sets the "option" for the X server to:
+    "grp:alt_shift_toggle,grp_led:scroll"
+  and the "layout" to:
+    "us,<ir or (country code)>"
+
+This will override the key combination that you possibly have set in
+/etc/X11/xorg.conf.d/90-keyboard-layout.conf to toggle keyboards.
+
+But you can change the settings made by BiCon with a command like this
+one (after having started BiCon, of course):
+  setxkbmap \
+    -display "$DISPLAY" \
+    -layout "<layout1>,<layout2>" \
+    -option "<your options"> \
+    -print | \
+  xkbcomp -w 2 - "$DISPLAY"
+
+3) If started as bicon.bin, BiCon doesn't load any font or keyboard.
+You might prefer it that way if you want to keep your own settings.
+
+Reference: file bin/bicon.in in the source archive.
