Pyromaniac using 'ansitext' VDU implementation

Pyromaniac supports different VDU implementations. The base just outputs plain text, and shows control sequences within the output. However, the ‘ansitext’ VDU implementation converts some of the VDU control codes into ANSI, so that they take effect in terminals.

This example shows that the COLOUR (VDU 17) sequence is being converted into the simple ANSI colours.
