Building the GeoServer Styler plugin from trunk

• Download sources from svn

  $ svn export http://svn.opengeo.org/suite/trunk/styler
  

• Copy the whole styler folder to the www folder of your GeoServer data_dir
• Access styler from your browser using http://localhost:8080/geoserver/www/styler/index.html (assuming that you are on the machine where GeoServer runs and that the instance is called geoserver)
