   3 # Automake fragment to hook up a basic Autotest test suite into the
   4 # build.  It is expected that a testsuite.at file exists in $(srcdir).
   5 # The testsuite will be output to $(builddir)/testsuite.
   6 #
   7 # The DX_AUTOMAKE_COMPAT macro must be expanded by configure.ac to
   8 # provide necessary substitutions.
   9 #
  10 # You must define the AUTOTEST variable to the Autotest program (normally,
  11 # this is autom4te -l autotest).  You must also define the HAVE_AUTOTEST
  12 # Automake conditional which controls whether the testsuite-generating
  13 # rules are enabled (that is, if Autotest is available and works).
  14 #
  15 # The DX_PROG_AUTOTEST_AM macro may be used to set all of the above.
