[Dick Hollenbeck <dick@xxxxxxxxxxx>]

OK, I got a footprint library to convert from legacy to kicad format using the attached
command line python script.
It ran nicely, and quickly, without a fuss once I get it setup correctly.


Procedure I used, which is perhaps not optimal, but is one that worked:
(I'm open to suggestions on improvement.)


1) Build target _pcbnew after enabling scripting in cmake.
$ make _pcbnew


2) Changed dir to pcbnew
$ cd pcbnew
$ pwd
build/pcbnew



3) Entered following command line, script takes to arguments: oldLibPath & newLibPath
$ PYTHONPATH=. ../lib_convert.py /usr/local/share/kicad/modules/smd_dil.mod /tmp/smd_dil


4) inspect one footprint found in new librarypath /tmp/smd_dil
$ less /tmp/smd_dil/msoic-10.kicad_mod


Attached is one of the converted footprints, *.kicad_mod
Observations:

a) Layernames should be in English always (in a footprint, not a board).

b) The old footprint was deci-mils, the new one is mm.


c) The next thing I notice is the ugyly timestamps on the fp_lines.

Wayne or JP, do we need those time stamps on mere lines?
