[PVFS2-CVS] commit by pcarns in pvfs2/maint/build: mpich2-build.py

[CVS commit program]

Update of /projects/cvsroot/pvfs2/maint/build
In directory parlweb:/tmp/cvs-serv15609

Added Files:
	mpich2-build.py 
Log Message:
broke out a part of some scripts written by Wes Emeneker (thanks Wes!) and
added some minor tweaks.  mpich2-build.py downloads mpich2 and builds it
with pvfs2 support (assuming that pvfs2 has already been built with
pvfs2-build.sh)
