+# SYNOPSIS
+#
+# This program gets the list of supported keyboards from libDrakX and
+# generates a grub2 keyboard mapping file for each keyboard in the list.
+# It then generates the keyboard names file and the language to keyboard
+# mapping file that are used when generating the bootloader menus for
+# the Mageia ISOs.
+#
+# The grub2 keyboard mapping files are generated using the grub2-kbdcomp
+# program. The X11 keyboard layout and variant names are obtained from
+# libDrakX. The files (*.gkb) are stored in the 'layouts' subdirectory
+# of the current working directory.
+#
+# The keyboard names file consists of a list of paired identifier and
+# description strings. The identifier is the keyboard identifier used
+# in libDrakX. The description is the canonical keyboard description
+# provided by libDrakX. The file (kbd-names.txt) is stored in the
+# current working directory.
+# 
+# The language to keyboard mapping file consists of a map of language
+# identifier to keyboard identifier strings. The language identifier
+# is the standard language/country code used for specifying a locale
+# (e.g. en_US). The keyboard identifier is the default keyboard for
+# that language, as provided by libDrakX. The file (lang-kbds.txt) is
+# stored in the current working directory.
+#
+# The list of supported languages is read from the language names file
+# (lang-names.txt) that is used when generating the bootloader menus.
+# This file is expected to be found in the current working directory.
