# hilite.pl - perl code colorizer on an ANSI terminal (xterm / putty session)
# place this script in your path and make executable, e.g.
#   $ cp hilite.pl ~/bin/hilite
#   $ chmod 755 ~/bin/hilite
# then run it to colorize text output that contains perl, e.g.
#   $ svn diff /some/path/MyModule.pm | hilite
# and you get syntax colored text
