When I know, I'll tell you.
I think the answer depends in part on what you're trying to do. The
requirements for, say, an ACID-compliant database are much heavier than for
most applications. As far as regular applications go, I'd like to see:
- the above tested and debugged for Windows and MacOS;
- should it save the previous version of the file?
- if so, how many backup files should it keep?
- should it try to sync and flush the disk on saving the file?
- anything I haven't thought of?
Some of those (like the keeping of backups) is probably something that
should be given as an option to the end-user.
