-    A free distributed version control system. It provides a simple,
-    single-file transactional version store, with fully disconnected
-    operation and an efficient peer-to-peer synchronization
-    protocol. It understands history-sensitive merging, lightweight
-    branches, integrated code review and 3rd party testing. It uses
-    cryptographic version naming and client-side RSA certificates. It
-    has good internationalization support, has no external
-    dependencies, runs on linux, solaris, OSX, windows, and other
-    unixes, and is licensed under the GNU GPL.
