Version 0.5a
- Fixed bug in readconfig().
Marc 'HE' Brockschmidt <marc@marcbrockschmidt.de> 16 Feb 2003 00:35:37
Version 0.5
- Fixed PGP-Support (merging some code from tinews.pl). Seems to work well.
Marc 'HE' Brockschmidt <marc@marcbrockschmidt.de> 11 Jan 2003 3:46:57
- General cleanup of the code, changing some weird behaviour and so on.
Marc 'HE' Brockschmidt <marc@marcbrockschmidt.de> 11 Jan 2003 2:27:23
- Changed the name of the project. There was another postfaq before, so I
switched to yapfaq (yet another postfaq). I like the idea of a software-line
called ya-software for a possible commercial: "Buy ya software!"
