# Pjcolor v1.0
# Pjcolor is a small AWK script for formating and coloring "pijul change" command like output.
# At the same time providing sane theming capabilities(as far as AWK allows)

BEGIN {

    EOL = 999; # hack for "until the end of line"

    # In case you want to create your own pjcolor theme
    # Include it like here:
    #
    # @include "<your-custom-pjcolor-theme>"
    #
    # Also comment out existing default theme.

    # Also export your AWKPATH Environment Variable. This will allow AWK
    # to pick up your theme without need to provide full path.
    # Have Fun.
