# This file exists to support comm-central from building with mozilla-central
# as a subdirectory to building as a subdirectory of mozilla-central.
# In order to have mozconfig files that support building in either
# configuration during the transition, without duplicating the logic
# in every mozconfig file, there needs to exist a file that exists at the
# same path in mozilla-central and comm-central.
# This file gets included under two circumstances.
# 1. comm-central is being built as a subdirectory of mozilla-central.
# 2. comm-central is being built as a parent directory of mozilla-central,
# but `mach` was invoked from the objdir and thinks that $topsrcdir is
# the mozilla-central directory. If we detect this is the case, we fix
# $topsrcdir before proceeding.
# In either case, we then invoke the identically named file that lives in
# comm-central, which sets some variables that can be used by the rest of the
# mozconfig.
# Note that the top-level mozconfig file is in $2.
if [ "$(dirname "$2")" = "$topsrcdir" ]; then
# No weirdness

# Building with comm-central as top-level directory.
