# Description:
# Script to export XKB configuration files to keycode -> virtual key code keymaps that are
# easy to use in FreeRDP. This makes keymap maintenance easier to make as all bugs can
# simply be reported to the XKB Configuration Database project, and then this script can
# be used to export newer (and fixed) version of the XKB Configuration Database.
