M-x diff RET
M-x ediff RET
M-x ediff3 RET

In particular, ediff3 is useful to compare changes made at the same time
by coworkers:

                        A
                      /   \
                     B     C

>From a source document A, coworker b produces document B, and coworker c
produces document C.  ediff3 allows you to see what changes were made by
each, and allows you to interactively merge a new version of the
document with changes from either or both of the coworkers.
You need to keep around the original document A to do this of course,
otherwise you will have to use ediff-merge.
