Good idea. We'll do that instead.

Yes, I agree. I've heard from some people that they'd find it easier
to upgrade to the new bindings if they can use the new bindings with
older versions of Subversion. So, for that reason, we designed the
higher level bindings to only use functionality from Subversion 1.4.x.
It's certainly possible for us to "rev" the Python API just like we
rev the underlying C API so that people can make use of newer
features, if they want. If there is demand for this we can do it, but
I don't think it's crucial for our first release.

If the bindings are generated on Linux and copied to Windows, the
automatically generated bindings won't contain windows-specific
functions such as "svn_auth_get_windows_ssl_server_trust_provider".
Looking at the Subversion source, though, it looks like there are only
four functions that are available on some platforms but not other
platforms. We could easily make these functions available on all
platforms using a patch I've included below.
Besides the above, the API of the ctypes python bindings differs from
the SWIG Python bindings in some important ways:
1. Pool arguments are mandatory for low-level functions
2. We didn't divide up the low-level functions into several
submodules. All Subversion functions are in the csvn.core module.
3. There are no "short names" for low-level functions. You need to
reference the functions by their full names (e.g.
svn_client_get_ssl_server_trust_file_provider instead of
svn.client.get_ssl_server_trust_file_provider).
