The help message still needs some work. If I type: list_e3sm_tests e3sm_developer. It doesn't work. You have to type; ./list_e3sm_tests suites e3sm_developer

Which is odd. I'd like to suggest different behavior. list_e3sm_tests with no arguments will output all the test suite names like list_e3sm_tests lists does now. Then list_e3sm_tests e3sm_developer will list the tests in e3sm_developer.

The help string can then include the -toptions which it currently doesn't.

Can I also request a -t lcompsets option which will list the long name of the compsets.

[jasonb5]

@rljacob Yea I see I missed updating the help message.

I'll change the behavior back.

Would you rather have the -t lcompsets or --long?

[rljacob]

--longwould be fine. Whatever you think is best.

@rljacob Reverted the behavior, add the --long option, and finished up the description.
