The rsync code itself is not modular, I believe.  I think the author
thereof kind of took the approach of placing efficiency before all.
See:

http://www.samba.org/rsync/how-rsync-works.html ... especially the
section on "The Rsync Protocol"

I Googled librsync and got a hit, but that code is a rewrite of the
source base and seems to have little or no activity since 2004.

http://librsync.sourceforge.net/

That page writes: "librsync is not wire-compatible with rsync 2.x, and
is not likely to be in the future."  The current version of rsync is
3.0.7.
