librsync  2.0.1
Todo List
Global rs_delta_begin (rs_signature_t *)
Add a version of this that takes a rs_magic_number controlling the delta format.
Global rs_patch_begin (rs_copy_cb *copy_cb, void *copy_arg)

As output is produced, accumulate the MD4 checksum of the output. Then if we find a CHECKSUM command we can check it's contents against the output.

Implement COPY commands.

Global rs_trace_to (rs_trace_fn_t *)
Do we really need such fine-grained control, or just yes/no tracing?
