Very true - this is how the C code was developed, after all - the
different repository access mechanisms are plug-ins. However, at least
for the short term, you are doing a large amount of work to deliver
less functionality vs. JNI, and will have to deal with supporting new
features in subversion as they arrive.

You can have moves and copies as well as modifications in the local
working copy, the working copy directory (.svn) has to maintain
information to track this. Behavior for chained events for one commit,
copy same file
modify #2 version
delete #1 version
move #2 to have #1 filename
can get really, really hairy. You would have the benefit however of
being able to port the working copy tests from the subversion

That is different however, as CVS has no library interface, and thus
cannot have JNI bindings - the only way to use the CVS packages from a
java program is executing the program and parsing its output.
