How to automate the extraction of footprint data from a KiCad library using Python?
Automating the extraction of footprint data from a KiCad library can be done using Python scripting. The script provided extracts data from the '/usr/share/kicad/modules/Sockets.pretty' library, printing details of each footprint including name, reference, value, description, and pad positions:

```python
#!/usr/bin/python

from pcbnew import *

libpath = "/usr/share/kicad/modules/Sockets.pretty"
print ">> enumerate footprints, pads of",libpath

# Script to extract footprint data from the library
# ... (rest of the script)

for name in list_of_footprints:
    fp = plugin.FootprintLoad(libpath,name)
    # ... (print footprint and pad details)
```

This approach is valuable for designers needing to analyze or document the contents of a footprint library, streamlining the process of selecting the right components for PCB designs.
