# LibreWolf bootstrap-without-vcs.patch
#
# Author:        Malte Jürgens <maltejur@dismail.de>
# Description:   Allow mach bootstrapping without a VCS checkout
# Last Updated:  2023-03-15
# License:       MPL 2.0
#
# This patch allows you to use `./mach bootstrap` without a VCS checkout.
# You can use that command to bootstrap a Firefox build environment.
# This patch works by adding a stub `LocalRepository`, which suprisingly
# is enough to make the bootstrapping process work. This may break other
# things in mach, but we don't use those.
