### Editing - save
The code now can generate a saved copy of the profile as it parses the profile.
Use the command ```--command save``` with ```--output``` and a filename,
to process the file with info to stderr, and it will save an copy of the file
to the ```--output``` (unencrypted).
It may be shorter than the original profile by up to 512 bytes, as the
original toxic profile is padded at the end with nulls. So this code
can be extended to edit the profile before saving it.
## Specification
