[Patch/committed]: Explain PEF and XSYM files

[Patch/committed]: Explain PEF and XSYM files

[Tristan Gingold]

Hi,

I am committing this patch that explains (in a few words) what are the PEF and XSYM files.
Just in case (like me) you were/are wondering.

I haven't found any pointers to the now mysterious per xlib format.

Tristan.
