[AUCTeX-devel] Regarding temporary files

[Colin Jia Zheng]

AUCTEX leaves a bunch of temporary files in the tex file's directory.
This is annoying:
* Messy, and you cannot configure AUCTEX to remove _region_* files
  and the auto/ folder on closing the tex file
* Fails when the directory is read-only

Is it possible NOT to write intermediate files in the same directory?
eg /tmp/tmpXXXXX?  (This is what LyX does)

There's the Clean command, but its purpose is not to remove the
_region_* files, _region_.prv/, etc.

Regards,
Colin
