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.
