Tools for making a browseable graphical revision history of schematics.
- scripts/gitsch2ppm: extract schematics as PPM files from a specfific git revision - scripts/gitenealogy: show the commit history of a file, tracking renames - scripts/ppmdiff/Makefile, scripts/ppmdiff/ppmdiff.c: compare two PPM files and highlight differences - scripts/schhist2web: generate a browseable graphical revision history of schematics
