Some Mini-Howtos of Interest

Abstract

A little collection of Mini-Howtos for GNU/Linux systems trying to help solving everyday problems I have found in different aspects, from system administration to basic graphic edition or text processing. The howtos were prepared having Debian systems in mind, but they should be useful for other GNU/Linux systems as well.
