+# We support a fairly large range of possible variables. It is expected that all types of files in a test
suite
+# will belong in exactly one of the following variables.
+#
+# First, we support the usual automake suffixes, but in lowercase, with the customary meaning:
+#
+# test_programs, test_scripts, test_data, test_ltlibraries
+#
+# The above are used to list files that are involved in both uninstalled and installed testing. The
+# test_programs and test_scripts are taken to be actual testcases and will be run as part of the test suite.
+# Note that _data is always used with the nobase_ automake variable name to ensure that installed test data
is
+# installed in the same way as it appears in the package layout.
+#
+# In order to mark a particular file as being only for one type of testing, use 'installed' or 'uninstalled',
+# like so:
+#
+# installed_test_programs, uninstalled_test_programs
+# installed_test_scripts, uninstalled_test_scripts
+# installed_test_data, uninstalled_test_data
+# installed_test_ltlibraries, uninstalled_test_ltlibraries
+#
+# Additionally, we support 'extra' infixes for programs and scripts. This is used for support
programs/scripts
+# that should not themselves be run as testcases (but exist to be used from other testcases):
+#
+# test_extra_programs, installed_test_extra_programs, uninstalled_test_extra_programs
+# test_extra_scripts, installed_test_extra_scripts, uninstalled_test_extra_scripts
+#
+# Additionally, for _scripts and _data, we support the customary dist_ prefix so that the named script or
data
+# file automatically end up in the tarball.
+#
+# dist_test_scripts, dist_test_data, dist_test_extra_scripts
+# dist_installed_test_scripts, dist_installed_test_data, dist_installed_test_extra_scripts
+# dist_uninstalled_test_scripts, dist_uninstalled_test_data, dist_uninstalled_test_extra_scripts
+#
+# Note that no file is automatically disted unless it appears in one of the dist_ variables. This follows
the
+# standard automake convention of not disting programs scripts or data by default.
+#
+# test_programs, test_scripts, uninstalled_test_programs and uninstalled_test_scripts (as well as their
disted
+# variants) will be run as part of the in-tree 'make check'. These are all assumed to be runnable under
