Re: gEDA-user: Starting with geda - component footprints.

["Phil Taylor" <phil@xxxxxxxxxxxxxxxxxxxxxxxx>]

I don't use m4 foot libraries.  You might try drawing this part up yourself in
a 'file' type of footprint.  I usually do this for connectors.

You do it in text and save the file in a local directory that has all of your
custom components in it.  This way you can keep your footprints separate from
the application/install.

Look at the footprint (files) at luciani.org.  The filetypes are fairly opaque
at first.  

The master document for making footprints is:

http://www.brorson.com/gEDA/land_patterns_20050129.pdf

Totally worth the initial hassle as in time making footprints in a text editor
is really fast and really safe.

also, don't forget the PCB-tips wiki:
