## AM_MAINTAINER_MODE turns off "rebuild rules" that contain dependencies

## problem because if users try to build on a machine with
## the wrong versions of autoconf and automake, these files will be
## rebuilt with the wrong versions and bad things can happen.
## Also, CVS doesn't preserve dependencies between timestamps, so
## Makefiles will often think rebuilding needs to occur when it doesn't.
##
## By default, it is enabled. Users can configure with
## --disable-maintainer-mode to prevent running the autotools.
