Description:

XPN (X Python Newsreader) is a graphical newsreader written in Python with the GTK+ toolkit.
XPN is distributed with the GPL licence, you’ll found a copy of the licence inside the XPN archive.
An interesting characteristic of XPN is the complete portability. I use it a lot on Linux and Windows, however XPN should work wherever Python and GTK+2 work.

With XPN you can read/write articles on the Usenet with a good MIME support (better than some well known newsreaders).

XPN can operate with all the most diffuse charset starting from US-ASCII to UTF-8. When you edit an article XPN automatically chooses the best charset, however is always possible to override this choice.

There also other useful features like scoring, filtered views, random tag-lines, external editor support, one-key navigation, ROT13, spoiler char …
