  /* The Test Plan
     
     The filesystem function svn_repos_dir_delta exists to drive an
     editor in such a way that given a source tree S and a target tree
     T, that editor manipulation will transform S into T, insomuch as
     directories and files, and their contents and properties, go.
     The general notion of the test plan will be to create pairs of
     trees (S, T), and an editor that edits a copy of tree S, run them
     through svn_repos_dir_delta, and then verify that the edited copy of
     S is identical to T when it is all said and done.  */
