"""
Convenience function for archiving just the last set of restart
files to a given directory. This also saves files attached to the
restart set, such as rpointer files and necessary history
files. However, it does not save other files that are typically
archived (e.g., history files, log files).
Files are copied to the directory given by archive_restdir.
If link_to_restart_files is True, then symlinks rather than copies
are done for the restart files. (This has no effect on the history
files that are associated with these restart files.)
