[AccessD] Compare code in two databases

A client has a database that has been used by a department for a long
time.  Last month, the database was given to another department which
made a few minor modifications to several of the modules.  Now the
client wants to put the two versions back together so that both
departments will operate the exact same way by sharing the same front
end.

Is there a tool that can compare modules from different databases and
highlight the differences in the code?
