Details

Summary

Add a usage string and a defaults section that clarifies:

  • If no input files are given, f18 reads from stdin
  • If no input files are given, f18 dumps the parse tree.
  • The default behaviour is to exec F18_FC.
  • The fefault F18_FC setting is 'gfortran'

Adds a simple regression test which tests the top and tail of the help
screen and the exit status.

Depends on D84855

Hi Rich, sorry not to have replied to your other review. No one on the NV team needs f18 to read from stdin.
