ToDo Manager

Hello everyone. I want to share with you a small script I wrote days ago that I use to manage a plain-text ToDo list.

The usage is IMHO very simple and it is fully documented in the POD section. Just use perldoc.

Despite it was initially written for Unix like environments it works quite well also under Windows (it is all a matter of file management).

Hope you'll find it useful.
