Re: [AMBER-Developers] Backup file renaming?

The one disadvantage is that Fortran doesn't have portable file
manipulation commands, so file RENAME and DELETE are non-standard and
may require C library functions.

An alternative approach is to have a single file that contains 2 sets of
restart data, written with direct access. You can write restart data to
the inactive half, then change the active flag last.
