[mpich-discuss] Announcing the availability of mpich2-1.4

[Eric A. Borisch]

Pavan,

Nice to see this come out. I'll get the MacPorts version updated soon.

There's a quest in MacPorts to have a license type included in each
port description. (This is a step along the way to enabling some
binary distributions within MacPorts) .. what license do you think is
the best description for MPICH2?  MIT? BSD?

Thanks,
 Eric
