Package colour provides Quake-style colour formatting for Unix terminals.
The package level functions can be used to write to stdout (or strings or other files). If stdout is not a terminal, colour formatting will be stripped.
eg.
colour.Printf("^0black ^1red ^2green ^3yellow ^4blue ^5magenta ^6cyan ^7white^R\n")
For more control a Printer object can be created with various helper functions. This can be used to do useful things such as strip formatting, write to strings, and so on.
