WTD / What To Do v1.0, released under the GPL license, source code included.
WTD is a "to do list" manager for the CP/M operating system and the Z80 cpu.
It has been written in MESCC, and follows the format and rules of Gina Trapani and his todo.txt system.
You can download from my website.
By the way, it has been ported from MESCC to Pelles C for Windows in a hurry (more information on this soon).
