Bash script to enable custom xkb layouts stored somewhere in user's $HOME

customXkbLayout

#!/bin/bash
######################################################
# In order to use custom xkb layout, create a folder
# under your $HOME (.xkb, for instance), and place
# layouts file there (in this script uk and rus
# are layout files, they need to go to .xkb/symbols).
# This directory will be searched by xkbcomp.
# No need to store custom layouts under /usr/share/X11
