generate_global_tables.py
==========================

sym-lib-table / fp-lib-table at the library root use ${KIPRJMOD}, which
KiCad only resolves when this directory *is* (or is symlinked as) the
currently open project's directory. To use this library globally, across
every KiCad project, you instead need a custom environment variable (this
script defaults to MIKILAB) defined once in KiCad's Configure Paths, plus
a copy of the two tables that reference that variable instead of
${KIPRJMOD}.

This script writes:
    sym-lib-table.global
    fp-lib-table.global

at the library root, identical in content to sym-lib-table/fp-lib-table
except for the environment variable used in each URI. See README.md
section 1 for the full install steps.

Usage:
    python3 scripts/generate_global_tables.py [--env-var MIKILAB]
