Right -- it's a utility, not a library (though someone is working on
making it a library).  I'd recommend looking into the librsync project
instead, which implements the rsync algorithm in a way that can be used
by any program:

This will not allow you to build something that is wire-compatible with
rsync, though.

For an example file-transfer program that uses librsync, see the rZync
link on the above page (and keep in mind that was merely a test-bed, so
it's mainly useful for seeing how someone integrated librsync into an
rsync-like program).
