This might be something easy that I just can't think of, or it might be impossible and I'm crazy for asking - but anyway:
Is there a way for me to compare my site's WordPress files against those of a standard WordPress installation? I'm using WP as a CMS, and had to do some pretty involved code hacking to get it working the way we needed it to - not just in wp-content, but in wp-admin and wp-includes as well. The problem now is, I don't have it documented as well as I would like, and if we ever want to upgrade, it is guaranteed to break.
Optimally, I would just like to see which of my WordPress files have any changes from the originals. I don't need to see what the changes themselves are, I can figure it out from there.
Thanks in advance
