"""
Script to verify that the case is ready for submission.

Typical usage is simply:
   ./check_case

You can run this before running case.submit to:
  - Ensure that all of the env xml files are in sync with the locked files
  - Create namelists (thus verifying that there will be no problems with
    namelist generation)
  - Ensure that the build is complete

Running this is completely optional: these checks will be done
automatically when running case.submit. However, you can run this if you
want to perform these checks without actually submitting the case.
