# Convert a footprint library from one format to another, e.g. legacy to pretty.

# 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=. <path_to>/lib_convert.py /usr/local/share/kicad/modules/smd_dil.mod /tmp/smd_dil.pretty

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