What is a good way to show changes between two versions
I was wondering if there is any package that can accomplish a Word-like color scheme for different versions of the same file.
So, if I have the
doc.tex and then modify it to be
doc-v2.tex. I can somehow tell the package in question that this file is actually a different (newer) version of
doc.tex. And then it will put different color to the text that is new/modified in the
doc-v2.tex. Just like Word does when you have different revisions.
Is there any package that does something like that? Or do I have to manually change the color for each and every line that is different?
