Do you understand `editors' now, having read svn_delta_edit_fns_t in
svn_delta.h? I don't mean to sound condescending; I'm just trying to
figure out how much you've learned so far.
The `editor' arguments in svn_client_*() are all optional. They're
defined as "before" and "after" editors... which means their routines
will be called before and after editor-events take place. (We should
update the doc strings to say that they're optional!)
For example, look at svn_client_checkout(). If you call it like
svn_client_checkout (NULL, NULL, NULL, NULL,
SVN_INVALID_REVNUM, 0, NULL, pool)
Then you will end up with a working copy in a directory called
"working_copy_dir", which contains the latest version of the
'barproject' directory from the 'file:///home/foo/repo' repository.
(Note that the const char * arguments above actually need to be
created with svn_stringbuf_create()).
Now, suppose you have a GUI client. Every time a new file is added to
your working copy during a checkout, you want little yellow chickens
to dance across the screen. Or maybe you just want a graphical
status-bar indicator. So... just write your own editor, and make its
add_file() routine do these things. Then pass your editor to
svn_client_checkout as an "after" editor. Voila.... extensibility.

Why do you need to use any code at all in svn_cl__* ?
The svn_cl__* code is the command-line client. You should definitely
look at it as an example of "how to use svn_client.h"... but you
shouldn't write JNI wrappers around them! Wrap svn_client.h and the
headers it immediately depends on.
