I would like to suggest to use `svn mv` and to place the ctypes python
bindings in ^/trunk/subversion/bindings/ctypes-python directory. The name
of the 'bindings' directory informs that its subdirectories contains
Subversion bindings.

Some high-level functions use deprecated Subversion functions, e.g. new depth
functionality isn't used. Can ctypes python bindings be updated to use
new functions?
