gEDA-user: PCB footprints quick reference added to wiki.

["Phil Taylor" <phil@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

I added notes on the PCB footprint file format to the PCB Quick Reference on
the wiki at:

http://geda.seul.org/dokuwiki/doku.php?id=geda:pcb-quick_reference

The goal is to help users write their own footprints and have quick access to
the easy-to-forget parts of the file-format.  Like what flags and
'clearance/2' means.

Please post or make additions and edits!
