OpenSource Solutions
The basic idea behind open source is very simple: When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, and people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.

Mentis develops and use OpenSource Solutions using Linux, Solaris or on any UNIX flavors.
