there is difflib

However, from your description, it looks like you are trying to achieve what
many modern SCM tools do already out-of-the-box, so why are you trying to
re-invent the wheel?

For example, SVN handles anonymous download of working copies with HTTP,
distributed SCM tools (bzr, git, mercurial, to name a few) allow you to copy
complete repositories over the internet, and merge/update them (as well as
sending patches back by eg email).

Such a solution reduces your problem mostly to a one line script like 'svn
update'. You may want to add a nice GUI front-end around it (although given the
fact you are offering them a repository with sources (which, presumably is more
advanced than point-and-click), I don't really see the need for a
point-and-click solution).
