 This approach might be applicable to other distributed VCSs as well, although they're not as oriented
 towards transmitting changes with standalone patch bundles (often by email) as darcs is.

 had to invent an ugly hack just for the purpose.
 
+By design, Git backend uses a "master-clone" repository pair approach in contrast
+to the single repository approach (here, _clone_ may be considered as the working
+copy of a fictious web user).  Even though a single repository implementation is

+By exploiting the fact that the master repo and _web user_'s repo (`srcdir`) are all
