Hi Doug,

I'd be interested in the trampoline program.

At the moment we are operating in a homogeneous computing environment.
Sooner or later we will add some a different computer architecture to
our pool and I was thinking about how to take advantage of compiling
byte-code once and using it on all platforms.  This has the advantage
that a developer can compile once, on any one platform, and make that
program immediately available on all other machine architectures.

I'm not sure of the best way to do this.  I was thinking of using the
bash MACHTYPE environment variable and then install the byte-code
program in /usr/local/bin but have the 1st line of that file say

   #! /usr/local/bin/ocamlrun.$MACHTYPE

Unfortunately the loader does not perform environment variable
expansion.  I tried other tricks but I couldn't find a simple "1
liner".  I'm still looking for something simple.  If anyone has any
ideas I'd like to hear them.

(Yes, there are probably automount tricks I could use but I'm looking
for a solution that will work for people without administrator
privileges.)
