that Andreas has been working so hard on. I think this is the single most awesome commit I've ever had the pleasure of committing. The results of this commit are described on http://trac.openlayers.org/wiki/Styles: essentially, this makes it possible to style features in all kinds of fun ways based on rules, and will also form the underlying basis for #533. Things this patch adds: * OL.Rule classes. These classes allow you to do tests against the propertie of a feature, and set a style based on these properties -- so you can compare the 'speedlimit' property of a line, and test if it is > 60, and if it is greater than 60, render it in a different color. You can also test combinations of rules using the OL.Rule.Logical class, and test featureids with the FeatureID class. * OL.Style class: The OL.Style class lets you wrap up Rules into styles that can be used with drawFeature to draw the feature in the selected style. * OL.Layer.Vector.drawFeature will check if the given style is an OL.Style object, and if so, it will draw the feature accordingly. examples/georss-flickr.html shows usage of these classes. Many, many thanks go to Andreas for all his hard work on this: this code really is very pretty, and includes unit tests for all the classes (and we know that I am a big fan of tests.) Three cheers for Andreas: Hip hip, hooray! hip hip, hooray! hip hip, hooray! git-svn-id: http://svn.openlayers.org/trunk/openlayers@5429 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf

Getting OpenLayers
------------------
OpenLayers lives at http://www.openlayers.org/.
You can get OpenLayers from
http://trac.openlayers.org/wiki/HowToDownload.
---------------------
Installing OpenLayers
---------------------
You can use OpenLayers as-is by copying build/OpenLayers.js and the
entire theme/ and img/ directories up to your webserver, putting them
in the same directory. The files can be in subdirectories on your website, or right in the root of the site, as in these examples. To include the OpenLayers library in your web page from the root of the site, use:
<script type="text/javascript" src="/OpenLayers.js" />
As an example, using bash (with the release files in ~/openlayers ):
$ cd /var/www/html
$ cp ~/openlayers/build/OpenLayers.js ./
$ cp -R ~/openlayers/theme ./
$ cp -R ~/openlayers/img ./
If you want to use the multiple-file version of OpenLayers (for, say,
debugging or development purposes), copy the lib/ directory up to your
webserver in the same directory you put the img/ folder. Then add
the following to your web page instead:
<script type="text/javascript" src="/lib/OpenLayers.js" />
As an example, using bash (with the release files in ~/openlayers ):
$ cd /var/www/html
$ cp -R ~/openlayers/lib ./
$ cp -R ~/openlayers/theme ./
$ cp -R ~/openlayers/img ./
------------------------------------
Using OpenLayers in Your Own Website
------------------------------------
The examples/ directory is full of useful examples.
Dcumentation is available in the doc/ directory: to build an HTML version
of the documentation, run ./docs.sh in the build/ directory.
Information on changes in the API is available in news.txt.
