It's cool!

I've tried, patched and have some comments.
(Attached patch is to work with subversion 1.4 binding
 and python 2.3)

I'm interesting in what feature of latest binding (1.5?) is
required. I tried it to work with 1.4.x binding with attached
patch and it seems ok. (not yet checked enough against converted
repos)

With svn 1.4, I should remove heading '/' from path
passed to API on the case of http: url.
See attached a patch.

+x can be get as svn:external in return value of ra.get_file().

> - - Move, rename info not propagated from SVN

I hope it would be in future version!

> - - Always requests whole file from SVN instead of diffs

# I doubt svn delta editor in python binding doesn't work...

Sure, but it can be found tracking directory change.

And more suggestion (for convert-repo, not only for svn):
 * Progress display on each stage will help us on converting
   non-small repo.
 * Create target repo if not exist.
 * When optional second arg is omitted, convert-repo try to
   use url + '-hg' as dest. It's not good.


And attached patch is a change not using ra access in
callback of ra.get_log(). It is required for svn 1.4 binding
at least.
I've successed converting small repository with
file:/http:/svn+ssh: urls.

But failed on another middle size repo. I didn't figure out the
reason yet, but maybe move/copy related thing.

Anyway, I'm grad to see this tool.
Thanks!
