Savecalc

This script is designed to save the most important output files from a run, in case you need to do long ionic optimizations involving several runs.

Advice: Use it as a security control in your run generator (see rungen), to avoid the accidental loss of information for submitting a job without previously moving the CONTCAR file into the new POSCAR.
