Updating a template

[ModProg]

We discussed this earlier, but I have a few ideas that should make this viable:

1. from from either a tag e.g. "0.1" or from a commit sha 0c4a3.
2. Modes for cleaning up files generated by from version
   a. force-clean: Delete all files that were created by from version
   b. try-clean: Check if any files created by from version were changed, if yes fail.
   c. partial-clean: Only delete all the files that were not changed
3. Modes for generating new files
   a. force-gen: Replace existing files with newly generated ones
   b. try-gen: Fail if any files would be overwritten
   c. partial-gen: Only generate files that would not overwrite existing ones.
4. Have combined modes, i.e. force, try, partial
5. For values:
   a. have some form of input file
   b. just respecify all the values, as they might have changed from version to version as well.

With a vc project you can just use force and than have a look at the diff.

This is probably a more complex problem, but if you are generally interested in this I'd do some investigating.
