# ===================================================================================

# ===================================================================================
#
# SYNOPSIS
#
# AX_MAINTAINER_MODE_AUTO_SILENT
#
# DESCRIPTION
#
# Set autotools to error/sleep settings so that they are not run when
# being erroneously triggered. Likewise make libtool-silent when libtool
# has been used.
#
# I use the macro quite a lot since some automake versions have the
# tendency to try to rerun some autotools on a mere make even when not
# quite in --maintainer-mode. That is very annoying. Likewise, a user who
# installs from source does not want to see doubled compiler messages.
#
# I did not put an AC_REQUIRE(MAINTAINER_MODE) in here - should I?
