Usage: $(basename "$0") [OPTIONs] DIRECTORY

Lists the tests (source/binary) available from the DIRECTORY directory
and down.

  --buildonly     List only tests that require building
  --runnable      List only tests that are executable
                  If you just want to build a test, but not run it,
                  do not include a main function into the .c file or
                  name it something including the "-buildonly" string.
  --test-tools	  List all test tools that require building.
  --help          Show this help and exit

Filenames need to follow some standarized format for them to be picked
up by this tool. This might change in the future. So far, the ones
picked up are:

NUMBER-NUMBER.c     [requires compilation]
NUMBER-NUMBER.sh    [does not require compilation]
NUMBER-buildonly.c  [requires compilation]
NAME.sh             [does not require compilation]

Note that the [requires compilation] tags will mean that the actual
test name for TEST.c after compiling will be TEST. Currently it does
not support TESTs compiled from many different sources.
