Automating properties in doc

[Michael D. Godfrey]

Rik,

You pointed out that:

## In Octave
unlink doctmp
diary doctmp
set (0)
diary off
exit

could be used as part of making the graphics properties
automatically generated from octave. I noticed that:

oct --eval "unlink doctmp; diary doctmp;set (0);diary off;"

does the same thing, and is a bit simpler. Right?

So, if you have a spare few minutes could you indicate
where these calls (and the perl call) should go?
In genprops.awk? Or?

Anyhow, I think that the patch I submitted yesterday
does the right thing for now, but automating the
property generation will ensure that it does not drop
out of sync again soon.
