 About
 -----
 
 ``RhodeCode`` is a fast and powerful management tool for Mercurial_ and GIT_ 
 with a built in push/pull server and full text search and code-review.
 It works on http/https and has a built in permission/authentication system with 
 the ability to authenticate via LDAP or ActiveDirectory. RhodeCode also provides
 simple API so it's easy integrable with existing external systems.
 
 RhodeCode is similar in some respects to github_ or bitbucket_, 
 however RhodeCode can be run as standalone hosted application on your own server.
 It is open source and donation ware and focuses more on providing a customized, 
 self administered interface for Mercurial_ and GIT_  repositories. 
-RhodeCode works on *nix systems and Windows it is powered by a vcs_ library 
+RhodeCode works on \*nix systems and Windows it is powered by a vcs_ library 
 that Lukasz Balcerzak and Marcin Kuzminski created to handle multiple 
 different version control systems.
 
 RhodeCode uses `PEP386 versioning <http://www.python.org/dev/peps/pep-0386/>`_
 
 Installation
 ------------
 Stable releases of RhodeCode are best installed via::
 
     easy_install rhodecode
 
 Or::
 
     pip install rhodecode 
 
 Detailed instructions and links may be found on the Installation page.
 
 Please visit http://packages.python.org/RhodeCode/installation.html for
 more details

 RhodeCode Features
 ------------------
 
 - Has its own middleware to handle mercurial_ protocol requests. 
   Each request can be logged and authenticated.
 - Runs on threads unlike hgweb. You can make multiple pulls/pushes simultaneous.
   Supports http/https and LDAP
 - Full permissions (private/read/write/admin) and authentication per project. 
   One account for web interface and mercurial_ push/pull/clone operations.
 - Have built in users groups for easier permission management
 - Repository groups let you group repos and manage them easier.
 - Users can fork other users repo. RhodeCode have also compare view to see
   combined changeset for all changeset made within single push.
 - Build in commit-api let's you add, edit and commit files right from RhodeCode
   interface using simple editor or upload form for binaries.
 - Mako templates let's you customize the look and feel of the application.
 - Beautiful diffs, annotations and source code browsing all colored by pygments. 
   Raw diffs are made in git-diff format, including git_ binary-patches
 - Mercurial_ branch graph and yui-flot powered graphs with zooming and statistics
 - Admin interface with user/permission management. Admin activity journal, logs
   pulls, pushes, forks, registrations and other actions made by all users.
 - Server side forks. It is possible to fork a project and modify it freely 
   without breaking the main repository. You can even write Your own hooks 
   and install them
 - code review with notification system, inline commenting, all parsed using
   rst syntax
 - rst and markdown README support for repositories  
 - Full text search powered by Whoosh on the source files, and file names.
   Build in indexing daemons, with optional incremental index build
   (no external search servers required all in one application)
 - Setup project descriptions and info inside built in db for easy, non 
   file-system operations
 - Intelligent cache with invalidation after push or project change, provides 
   high performance and always up to date data.
 - Rss / atom feeds, gravatar support, download sources as zip/tar/gz
 - Optional async tasks for speed and performance using celery_  
 - Backup scripts can do backup of whole app and send it over scp to desired 
   location 
 - Based on pylons / sqlalchemy / sqlite / whoosh / vcs
 
     
 Incoming / Plans
 ----------------
 
 - Finer granular permissions per branch, repo group or subrepo
 - pull requests and web based merges
 - per line file history
 - SSH based authentication with server side key management
 - Commit based built in wiki system
 - More statistics and graph (global annotation + some more statistics)
 - Other advancements as development continues (or you can of course make 
   additions and or requests)

   or use http://webchat.freenode.net/?channels=rhodecode for web access to irc.
 
 - You can also follow me on twitter **@marcinkuzminski** where i often post some
   news about RhodeCode
 
 
 Online documentation
 --------------------
 
 Online documentation for the current version of RhodeCode is available at
  - http://packages.python.org/RhodeCode/
  - http://rhodecode.readthedocs.org/en/latest/index.html
 
 You may also build the documentation for yourself - go into ``docs/`` and run::
 
    make html
 
 (You need to have sphinx_ installed to build the documentation. If you don't
 have sphinx_ installed you can install it via the command: 
 ``easy_install sphinx``)
