This tool comes in handy for organizing kicad footprints and modules. Unfortually it doesn’t build on osx normally. I have created a homebrew repo and after ignoring some build errors it seems to compile and work great on OSX.
The main site for the tool is at http://www.compuphase.com/electronics/kicadlibrarian_en.htm.
My homebrew repo is located at https://github.com/shaneburrell/homebrew-kicadlibrarian
