# Portability notes:
# To guarantee this script works on all platforms that support awesome
# please keep the following restrictions in mind:
#
# - don't use if ! command;, use command; if [ $? -ne 0 ];
# - don't use [ -e file ] use [ -r file ]
# - don't use $(), use ``
# - don't use ~, use ${HOME}
# - don't use id -u or $UID, use whoami
# - don't use echo -e
# - getopts won't work on all platforms, but the config-file can
# compensate for that.
# - various software like grep/sed/perl may be not present or not
# the version you have. for example grep '\W' only works on gnu-grep.
# Keep this in mind, use bare basic defaults.
# - Do _NOT_ suggest to use #!/bin/bash. Not everybody uses bash.
