Re: ROOT and Debian

Hi again,

I forgot to comment on a few things.

To me, it's not entirely clear just what licence cover use of Minuit.
As you know, CERNLIB has in the past re-licensed software rather
brutally.  Checking with Ian McLaren is probably not a bad idea.  If you
get a reply, please forward that to me and perhaps Fons too.

The buildd point is _very_ attractive to ROOT. 

This reminds me of another issue concerning ROOT.   Currently, I've only
tested the ROOT packaging scripts on Debian GNU/Linux on a i386 chip.
I've previously ported ROOT to Debian GNU/Hurd, but I haven't tried it
in a while.   However, ROOT build on many a platforms, including ia64,
Sparc, Alpha, and so on.  However, it is assumed that if you are
building for say a Sparc chip, you're using Solaris, and so forth.  It'd
be interesting to see what chips ROOT build on, assuming the normal
`linux' configuration.  If anyone out there's using some `port' other
than GNU/Linux on i386, of Debian, could you please give it a whirl to
see if it works?  Thanks. 

Concerning fonts.  I've one implemented a patch that did some hard-coded
alternatives stuff, but it wasn't very nice.  Something like that could
be revived.  The best option will be if upstream is changed.
