Notes

Python executable in PATH

This change allows user scripts to run with the same python interpreter as the payu process.

Set mppnccombine flags

The mppnccombine program collates tiled MOM model outputs as a post-processing step. There are now versions of this program in use that have different command line options which caused errors. This is fixed in this release by detecting the version of mppnccombine and using the appropriate command line options.
