This trivial package presents a simplified interface to
the most excellent
ansi-terminal package, exposing only
the functionallity that I personally use. It is very
limited, but very easy to use.
This package allows you to manipulate the text output terminal (assuming your program has one). Specifically, it supports colour changes and title changes (for virtual terminals). Impressively, it (or rather, the package it wraps) works on both Windows and Unix. Under Windows, it uses native Win32 calls, while under Unix it uses ANSI escape codes.
