Yes I had to change it, since fsm implies file system, but it is not

Already done. But I can see that it is still present in the README file.
Will fix it, tanks.

I could not find it on http://manpages.debian.net/cgi-bin/man.cgi but I
know there is a project called ssm:

ssm.i686 : Macromolecular coordinate superposition library

but my project is called System Storage Manager and ssm is just the
executable. I could not find any binary with the same name (within
Fedora), not sure if that will be a problem...
