/*! \mainpage Route-Me Map Framework 

\section intro_sec Introduction

Route-Me is an open source Objective-C framework for displaying maps on Cocoa Touch devices 
(the iPhone, and the iPod Touch). It was written in 2008 by Joseph Gentle as the basis for a transit
routing app. The transit app was not completed, because the government agencies involved chose not to release
the necessary data under reasonable licensing terms. The project was released as open source under the New BSD license (http://www.opensource.org/licenses/bsd-license.php) 
in September, 2008, and
is hosted on Google Code (http://code.google.com/p/route-me/).

 Route-Me provides a UIView subclass with a panning, zooming map. Zoom level, source of map data, map center,
 marker overlays, and path overlays are all supported.
\section install_sec Installation
 
Because Route-Me is under rapid development as of early 2009, the best way to install Route-Me is use
Subversion and check out a copy of the repository:
\verbatim
svn checkout http://route-me.googlecode.com/svn/trunk/ route-me-read-only
\endverbatim

 There are numerous sample applications in the Subversion repository.
 
 To embed Route-Me maps in your Xcode project, follow the instructions in the Embedding Guide at 
 http://code.google.com/p/route-me/wiki/EmbeddingGuide . To create a static version of Route-Me, follow these 
 instructions instead: http://code.google.com/p/route-me/source/browse/trunk/MapView/README-library-build.rtf
 
\section maps_sec Map Data
 
 Route-Me supports map data served from many different sources:
 - the Open Street Map project's server.
 - CloudMade, which provides commercial servers delivering Open Street Map data.
 - Microsoft Virtual Earth.
 - Open Aerial Map.
 - Yahoo! Maps.
 
 Each of these data sources has different license restrictions and fees. In particular, Yahoo! Maps are 
 effectively unusable in Route-Me due to their license terms; the Yahoo! access code is provided for demonstration
 purposes only.
 
 You must contact the data vendor directly and arrange licensing if necessary, including obtaining your own
 access key. Follow their rules.
 
 If you have your own data you'd like to use with Route-Me, serving it through your own Mapnik installation
 looks like the best bet. Mapnik is an open source web-based map delivery platform. For more information on
 Mapnik, see http://www.mapnik.org/ .
