run (x)emacs, type M-x ediff (thats meta (usually left-windows or
left-alt) and the 'x' key).
to do side-by-side, press '|' on the little ediff control window that
will pop up. '?' will give help.
(basically, 'n' and 'p' will step forward or backward through the
difference regions, 'q' will quit. 'w' will toggle making the window
as wide as possible, which is good for side-by-side.
pressing 'a' or 'b' will replace one region with the corresponding
region from the other file. 'r a' or 'r b' will undo ("revert") such
an action)
you can do merges, diffs, etc between files, buffers, arbitrary
regions, version-control revisions, etc. ediff/emerge is good.
