For what it's worth,

http://packages.debian.org/changelogs/pool/main/d/dime/dime_0.20030921-1/changelog

"dime (0.20030921-1) unstable; urgency=low

  * New upstream
  * ..."

The main changelog isn't updated though, so I don't know what that means
in practicable terms; only that it was updated somewhere between Jan 2002
and Sept 2003.

In 5.3 there is:
v.in.dxf, v.in.dxf3d, v.in.dxf3d.sh
v.out.dxf

Unless someone wants to do it themselves, I don't think there's much
point in spending too much time trying to get the v.in.dxf's working
with 5.7, it would be outdated before it was born..

AutoCAD should be able to read older formats (I would hope), even if it
won't write them, so updating v.out.dxf to 5.7's binary vector format +
features would still be a nice thing to have on the Wish list..
