What does dsfg as a part of package names mean?

Question

I know the general format for package names in Debian and Ubuntu. Some packages have additions to the standard numbering scheme with obvious meaning like svn20090426 etc. But also quite a few packages have dsfg in their name (e.g. 2:1.0~rc4~try1.dsfg1-1ubuntu1) – what does that mean?

Is it just a typo of the Debian Free Software Guidelines (DFSG)?

Solution

http://en.wikipedia.org/wiki/Debian_Free_Software_Guidelines

A package with 'dfsg'/'dsfg' suffix is one that has been stripped of any files that doesn't follow the Debian Free Software Guidelines.

So is dsfg indeed a typo and should be dfsg?

I see three source packages with that typo indeed...

Yes, I bet it's a typo :)

Typo means it is misspelled. It was said in the other answer that it is an acronym but with a typo. Notice that the s and f are mixed up.
