But how would doc-view know if the document has to be converted anew?
We could use such a dirname you suggested and add the md5 sum in a file.

The current implementation has the benefit that there will be no new
conversion if you have the document multiple times (or moved it to a new
location).

So both variants have benefits and drawbacks...

Yes, that could be nice.  But to get that right one would need access
timestamps.  AFAIK most users turn them off for their filesystem and I
don't know how portable this is anyway.

But a timestamp file could be added in the cache dir.

Do you have write access to the emacs CVS tree?  If yes it would be
great if you added an item about that to etc/TODO.

Then I'd open the document and hit `r' (or `g') after each latex run.  I
guess you can automate that somehow.
