#!/bin/bash
#
# This script is used to sync the upstream gcc repository, plus a series of
# other related toolchain repositories.
#
# It is highly dependant on the git setup Linaro has on its server. Setup that
# is done with gitolite and gitweb.
#
# How the mirrorin has been done:
# - mirrorin happens in /srv/mirror on the server
# - depending on the mirror type, we can create a git-svn clone in a separate
# directory, add a new remote on the "original" repo, and then make sure
# everything is pushed to the real bare repo.
#
# For more info: https://wiki.linaro.org/Platform/LAVA/Infrastructure/ToolchainsMirror
