This is a log colorizer perl script intended to have command output piped through it to a terminal, and allows easy file-based configuration of new highlighting schemes using simple text matches, globs or regular expressions.
It works transparently even in interactive contexts with scripts which produce prompt lines and wait for user input.
Patterns are provided for ant and maven output. See the readme on the main github page for instructions.
My version started as a fork of v1.1 from resentment.org, but I've made numerous improvements since then.
