Creating a complex tag with the list of files changed necessary for a bug correction

Hi everyone!

I was thinking of creating a tag that had the complete list of files I
had to change in order to do a bug correction on the software I'm
currently working on. Once I had changed some files and tested
everything, I want to create a tag after a commit with the complete
directories or files I had to change.

My question is just this one: what is the simplest way to do this?

I've thought on this problem and I think the best way to do this is to
create a script (or customize the post-commit hook script) that gets the
list of changed files and creates the tag for me. Has anyone done this
before or have a differente approach?

Best regards,
