Namely, that m requires an argument and not n as indicated to
getopt. This caused the help message to be printed whenever users
did not want exceptions to be thrown.
Additionally we fix the error message for options that need an argument
but do not get one.
- restartRegressionTest, initRegressionTest was squashed to one
application, which also supports integration test as well as test
of restart files (non-unified) and .RFT files.
- summaryRegressionTest was renamed compareSummary -- now it can
execute an integration test as well as regression test. Also other
improvements were made.
