-Soledad - Synchronization Of Locally Encrypted Data Among Devices.
-
-Soledad is the part of LEAP that manages storage and synchronization of
-application data. It is built on top of U1DB reference Python API and
-implements (1) a SQLCipher backend for local storage in the client, (2) a
-SyncTarget that encrypts data before syncing, and (3) a CouchDB backend for
-remote storage in the server side.

-"""
-A U1DB backend that uses SQLCipher as its persistence layer.
-
-The SQLCipher API (http://sqlcipher.net/sqlcipher-api/) is fully implemented,
-with the exception of the following statements:
-
-  * PRAGMA cipher_use_hmac
-  * PRAGMA cipher_default_use_mac
-
-SQLCipher 2.0 introduced a per-page HMAC to validate that the page data has
-not be tampered with. By default, when creating or opening a database using
-SQLCipher 2, SQLCipher will attempt to use an HMAC check. This change in
-database format means that SQLCipher 2 can't operate on version 1.1.x
-databases by default. Thus, in order to provide backward compatibility with
-SQLCipher 1.1.x, PRAGMA cipher_use_hmac can be used to disable the HMAC
-functionality on specific databases.
-
-In some very specific cases, it is not possible to call PRAGMA cipher_use_hmac
-as one of the first operations on a database. An example of this is when
-trying to ATTACH a 1.1.x database to the main database. In these cases PRAGMA
-cipher_default_use_hmac can be used to globally alter the default use of HMAC
-when opening a database.
-
-So, as the statements above were introduced for backwards compatibility with
-SLCipher 1.1 databases, we do not implement them as all SQLCipher databases
-handled by Soledad should be created by SQLCipher >= 2.0.

-General info
-------------
-
-Test files in this directory are derived from u1db-0.1.4 tests. The main
-difference is that:
-
-  (1) they include the test infrastructure packed with soledad; and
-  (2) they do not include c_backend_wrapper testing.
-
-Dependencies
-------------
-
-u1db tests depend on the following python packages:
-
-  nose2
-  unittest2
-  mercurial
-  hgtools
-  testtools
-  discover
-  oauth
-  testscenarios
-  dirspec
-  paste
-  routes
-  simplejson
-  cython
-
-Running tests
--------------
-
-Use nose2 to run tests:
