# bash autocomplete, that can work with:
# a) --help of program
#
# Also you may like:
# $ bind "set completion-ignore-case on"
# $ bind "set show-all-if-ambiguous on"
#
# It uses bash-completion dynamic loader.
# Known to work with bash 3.* with programmable completion and extended
# pattern matching enabled (use 'shopt -s extglob progcomp' to enable
# these if they are not already enabled).
