This script will prep a 'main' reSIProcate checkout to
use the autotools (new) build mechanism.

After running this script, the working directory will
have files related to the build process moved to the

Also, files related to the OLD build mechanism will be 
removed.  They are only removed on this branch in SVN.
A vanilla 'main' checkout will still contain these files.
