GTKMan is a simple GTK+2 manual page viewer, written in Python. Manual pages are viewed by specifying their name and optionally the section they are in, just as with the original man command. The manual pages are displayed in simple text form using the default system monospace font.
GTKMan is available in many different languages. The translation project is located at transifex.net and you can help with translating in your language using the respective resource at the following URL: http://www.transifex.net/projects/p/salix/resource/gtkman
GTKMan is currently available as a package from the Salix repositories and users can install it using slapt-get or Gslapt.
Source tarballs for all gtkman releases can be found at: http://people.salixos.org/gapan/gtkman/
The source code is also available through git. You can clone/fork it at github: https://github.com/gapan/gtkman
