Usage: run-test [OPTION...] CHECKER PROGRAM [ARGUMENT...]
Runs PROGRAM under the control of CHECKER.
CHECKER may be empty or a valgrind command with some options, such as
'valgrind --tool=memcheck --num-callers=20 --leak-check=yes --leak-resolution=high --show-reachable=yes'.
When CHECKER is not empty, it is recommended that the package has been
configured with
--disable-shared so that tests are real executables and not libtool
wrapper scripts, and
CFLAGS=\"-g\" so that valgrind shows line numbers.
Send patches and bug reports to <bug-gnulib@gnu.org>."
