# 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?
