cw is a non-intrusive real-time ANSI color wrapper for
common Unix-based commands. It is designed to simulate
the environment of the commands being executed, so that if
a person types 'du', 'df', 'ping', etc. in their shell it will
automatically color the output in real-time according to a
definition file containing the color format desired. It has
support for wildcard match coloring, tokenized coloring,
headers/footers, case scenario coloring, command-line-
dependent definition coloring, and includes over 50 pre-
made definition files.
