37  * Tests gmx::CommandLineHelpWriter.
38  *
39  * These tests fail for any change in the output, and it should be reviewed
40  * whether the change was intentional.
41  * For development, the tests can be run with a '-stdout' command-line option
42  * to print out the help to stdout instead of using the XML reference
43  * framework.
