# switchkeys: A little script to switch between two keyboard layouts
# in the Linux console and XFree86. You need to edit the top of this
# file to change the paths to the layout files. Also note that the
# PATH is not set in this script, so you may wish to set it here to
# ensure proper operation. Requires awk and the relevant programs to
# set keyboard maps, does not check to see if they exist. The detection
# algorithm for the current layout may also break easily. All in all,
# not a robust script, but works for me.
