[Sheflug] Latex Question

[José Luis Gómez Dans <xxxxx [at] xxxxxxxxxxxxxxx>]

Hi,
	I am in the process of iterating the writing of a paper in
Latex. What I'd really like to see is how to hightlight changes in each
version of the document. What I'd really like is to have some sort of
"diff" in the dvi file, which indicates which parts have changed or not.
Suppose a column looks like this:

	blahblahblahblahhh
	blahblahblahblahhh
	rhubarbrhubarbblah |
	blahblahblahblahhh

	As the 3rd line has been modified, we get a little line, * or
whatever next to it indicating it has changed.

	Ihave search on CTAN, but found nothing, so presumably, it ain't
possible (or it is too much of a hsssle).

	Any pointers welcomed,
	José
