+# #!/bin/sh
+# . "${srcdir=.}/init.sh"; path_prepend_ .
+# Execute some commands.
+# Note that these commands are executed in a subdirectory, therefore you

+# Note that the "path_prepend_ ." is useful only if the body of your
+# test invokes programs residing in the initial directory.
+# For example, if the programs you want to test are in src/, and this test
+# script is named tests/test-1, then you would use "path_prepend_ ../src",
+# or perhaps export PATH='$(abs_top_builddir)/src$(PATH_SEPARATOR)'"$$PATH"
