+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.
