In short terms, saccharin is just another UI for 0install
infrustracture, so you need just cook proper 0install feed(it could be
bundled to .xo or saccharin could use web link to your feed). See [3]
for 0install packaging tutorials.

There is only one difference - saccharin could use 0install feed not
to launch final application(the final target of feed is describing
how to install/launch such application) but using feed's dependencies
as a activity dependencies[4] (saccharin will just fetch/build/install
dependencies and w/o launching feed's application, will run regular
activity). But saccharin could be used for launching regular 0install
applications as well[5] (it depends on what arguments were passed to
injection command).
