What it does: A perl script that converts TAClog .CW file (Text format) to Tucnak (tucnakcw) format.

Why? As a TACLog user you'll have built up a valuable .CW file. Convert it to text mode (see the TAClog documentation) and then convert for use in Tucnak (either v2 or v3).
This program is also distributed with the linux version of Tucnak 2.
