# Automake fragment to hook up a basic Autotest test suite into the
# build.  It is expected that a testsuite.at file exists in $(srcdir).
# The testsuite will be output to $(builddir)/testsuite.
#
# The DX_AUTOMAKE_COMPAT macro must be expanded by configure.ac to
# provide necessary substitutions.
#
# You must define the AUTOTEST variable to the Autotest program (normally,
# this is autom4te -l autotest).  You must also define the HAVE_AUTOTEST
# Automake conditional which controls whether the testsuite-generating
# rules are enabled (that is, if Autotest is available and works).
#
# The DX_PROG_AUTOTEST_AM macro may be used to set all of the above.

# With older Automake the stubs are generated directly in config.status.
