Why $0 is used here in the first place? The previous > version used $SYSDIR and it looks more reasonable to me. >=20 $0 is used to speed up execution of svnversion when evaluating if the ${svnversion} is compatible with the tree.

But, I am at the point now of being ready to revert all these changes back to the original newvers.sh before I added svnliteversion...
