[9fans] psutils et al

[nemo@gsyc.escet.urjc.es]

Yep. I knew them, but almost all of them I tried in Linux either
did not work as they said, or broke the postscript. Nevertheless,
mpage -1 -l worked fine in linux. Perhaps it's time to consider a
port of mpage to Plan9, since my problem was that I was
unable to do this under plan9.

I read the gs documentation and seems that viewers that
do the rotate thing are using postscript routines to change
the page orientation, so I think that unless page could go the
same way, there is no simple gs option to rotate the ps.
In any case, I'd say that's  the job of a filter and not of
page.

hth to others with the same problem.
