# 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 $(builddir)/testsuite.
#
# You must define the AUTOTEST variable to the Autotest program (normally,
# this is autom4te -l autotest).  The DX_PROG_AUTOTEST macro can be used
# to set this automatically.  You must also define the HAVE_AUTOTEST Automake
# conditional which controls whether the testsuite-generating rules are
# enabled.  If DX_PROG_AUTOTEST is used, this may be set like:
#
#   DX_PROG_AUTOTEST
#   AM_CONDITIONAL([HAVE_AUTOTEST], [test x"$dx_cv_autotest_works" = x"yes"])
