Free & Open Source
mMass belongs to the wide family of open source software. It is written mostly in Python language, uses wxPython libraries for graphic user interface and is released under GNU General Public License. Therefore it is portable to different computer platforms and has a good potential to be easily modified or extended by modules of specific needs.
