1) Send "cvs diff" output to this list
2) Use ".cvsrc" from build-tools/ repository
  ("diff -uNp" is key here)
3) If the diff is more than 100-200 lines, post a URL instead

I think I, tausq, ESIEE, willy should review/try it.

Ok. You might also want to put a URL of your tarball of programs...perhaps
some debian types on debian-hppa would be interested in creating
a debian package of those.

Cool! if you could keep those changes seperate for now...that
might make life easier in case we want to send those changes
back "upstream" (to SGI I assume).

heh...if you know it will break another arch, leave it alone.

Even folks outside the support center think it's a good idea.

I can't promise anything. You know what I want.
Comments/guidance from Alan Cox and/or Matthew Wilcox would be good here.
