# mozconfigfind - Loads options from .mozconfig onto configure's
# command-line. The .mozconfig file is searched for in the
# order:
# If $MOZCONFIG is set, use that.
# If one of $TOPSRCDIR/.mozconfig or $TOPSRCDIR/mozconfig exists, use it.
# If both exist, or if various legacy locations contain a mozconfig, error.
# Otherwise, use the default build options.
