#
# Usage:
# versions [[case_insensitive_strings] ...]
#
# Quick way to list _personally relevant_ versions of software on a computer.
# If 'substring' is given output is limited to lines containing it.

# If called with one (string) argument, run this very script
# with no arguments but grep for the string and exit.

# De facut:
#    - LOOP OVER ARGS!!!
#    - de mutat functia in alt fisier?
#    - de mutat fiecare componenta in fisiere separate: check_gcc, check_perl etc
#    - LOOP OVER check_* FILES FOUND IN THE DIRECTORY 'selected' !!!
