-Leap SMTP Relay
-===============
-
-Outgoing mail workflow:
-
-    * LEAP client runs a thin SMTP proxy on the user's device, bound to
-      localhost.
-    * User's MUA is configured outgoing SMTP to localhost
-    * When SMTP proxy receives an email from MUA
-        * SMTP proxy queries Key Manager for the user's private key and public
-          keys of all recipients
-        * Message is signed by sender and encrypted to recipients.
-        * If recipient's key is missing, email goes out in cleartext (unless
-          user has configured option to send only encrypted email)
-        * Finally, message is relayed to provider's SMTP relay
-
-
-Dependencies
-------------
-
-Leap SMTP Relay depends on the following python libraries:
-
-  * Twisted 12.3.0 [1]
-  * zope.interface 4.0.3 [2]
-
-[1] http://pypi.python.org/pypi/Twisted/12.3.0
-[2] http://pypi.python.org/pypi/zope.interface/4.0.3
-
-
-How to run
-----------
-
-To launch the SMTP relay, run the following command:
-
-  twistd -y smtprelay.tac
-
-
-Running tests
--------------
-
-Tests are run using Twisted's Trial API, like this:
-
-  trial leap.email.smtp.tests

-Soledad -- Synchronization Of Locally Encrypted Data Among Devices
-==================================================================
-
-This software is under development.
-
-Dependencies
-------------
-
-Soledad depends on the following python libraries:
-
-  * u1db 0.1.4 [1]
-  * python-swiftclient 1.2.0 [2]
-  * python-gnupg 0.3.1 [3]
-  * CouchDB 0.8 [4]
-  * hmac 20101005 [5]
-
-[1] http://pypi.python.org/pypi/u1db/0.1.4
-[2] http://pypi.python.org/pypi/python-swiftclient/1.2.0
-[3] http://pypi.python.org/pypi/python-gnupg/0.3.1
-[4] http://pypi.python.org/pypi/CouchDB/0.8
-[5] http://pypi.python.org/pypi/hmac/20101005
-
-
-Tests
------
-
-Soledad's tests should be run with nose2, like this:
-
-  nose2 leap.soledad.tests
-
-Right now, there are 3 conditions that have to be met for all Soledad tests to
-pass without problems:
-
-  1. Use nose2.
-  2. Have an http CouchDB instance running on `localhost:5984`.
-  3. Have sqlcipher configured (using LD_PRELOAD or LD_LIBRARY_CONFIG to point
-     to the place where libsqlite3.so.0 is located).

-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:
-
-  nose2 leap.soledad.tests.u1db_tests
