This holds the client code for application sync. Some integration
code exists in addons/jetpack/ and site/jsapi/sync*.
The tests are doctests, and are
located in sync/tests/. These are not directly runnable, you should
use the appsync server.
Once you are running the server, go to http://localhost:5000/sync/tests/
To make use of sync you also really need the server: appsync
There are instructions on that page to run the server. Note you
should probably edit etc/appsync-dev.ini and uncomment the
appropriate lines in [storage] to use MySQL or SQLite (SQLite being
the simplest).
The server is also needed to run the tests.
