kicad/scripts/library-repos-install.sh

#!/bin/bash
# Git KiCad library repos:
#
# The "install_prerequisites" step is the only "distro dependent" one.  Could modify
# that step for other linux distros.
# This script requires "git".  The package bzr-git is not up to the task.
# The first time you run with option --install-or-update that is the slowest, because
# git clone from github.com is slow.
# After that updates should run faster.

# There are two reasons why you might want to run this script:
#
# 1) You want to contribute to the KiCad library team maintained libraries and have yet to
#    discover or have chosen not to use the COW feature in the Github "Plugin Type".
#
# 2) You want to run with local pretty footprint libraries and not those remotely located
#    on https://github.com using Github plugin.  After running this script you should be able to
#      a)  $ cp ~/kicad_sources/library-repos/kicad-library/template/fp-lib-table.for-pretty ~/fp-lib-table
#    and then
#      b) set your environment variable KISYSMOD to "~/kicad_sources/library-repos".
#         Edit /etc/profile.d/kicad.sh, then reboot.
#
#    This will use the KiCad plugin against the *.pretty dirs in that base dir.


# Set where the library repos will go, use a full path
