Just wanted to be a bit of help :-)

I see, I didn't know that.

O.k.

Yes, that would be the best. Probably the GDAL could help here.

I don't think this ifdef is required. I had to add it to r.in.dem as
well (for MacOS). The Linux likes it, too. It's present on SUN/Solaris.
On CRAY it is o.k., too. What about SGI?

Mhh, I don't get it. You think to maintain MAN format? At least I
don't know how to write it (HTML is much easier). If you think of an
*online* version, please consider that many users don't have
permanent access (or access at all, those CDROM users).

Yes, probably we need PERL as requirement...

Hi John! Any suggestions?

Andreas, did you see this:

I don't know if it is the right thing.
