The second section of "doc/unrolling.txt" explains the changes that you'll 
need to make to "cvm_config.h" to turn on the unroller.  The changes for 
"cvm.c" are already done.  At the top of "unroll.c", you'll need to add the 
following two lines just before the "#error" case:

    #elif defined(CVM_PPC)
        #include "md_ppc.h"

Then fix any compilation bugs that arise.  After that, run some simple "Hello 
World" style test cases, relax, and watch the pretty segfaults. :-)  The 
bottom of "unrolling.txt" describes some techniques for debugging.

Once there are no more segfaults and "make check" runs successfully in 
pnetlib, then you're in good shape.

Cheers,

Rhys.
