CDN build process
===================
Run the cdnBuild.sh script to generate the CDN distributions for the Google and AOL CDNs. Be sure to:
- use a pristine svn export of a tag and run cdnBuild.sh from the util/buildscripts directory in that tag.
  svn export https://svn.dojotoolkit.org/src/tags/release-1.4.3 1.4.3
- make sure sha1sum is available on the OS, otherwise the signature generation will fail.
- Apache Ant is needed to run the cldr i18n resources. the cldr build process does not work with 
  Ant 1.7.0, but does work with Ant 1.7.1 and 1.6.5. Download one of those and do this to set the version of Ant to use:
  export ANT_HOME=/full/path/to/ant-1.7.1

The result will be in the svn exported tag directory's release/VERSION-cdn directory.

After doing the build, place the VERSION-cdn directory on the dojotoolkit.org site and notify the CDN owners.
Let the know the .zip file's sha signature is in the sha1.txt file at the top, and ask them to update
their symlink for the MAJOR.MINOR version number to the latest MAJOR.MINOR.PATCH number.

An example based on the AOL CDN: if releaseName was 1.3.1, then update http://o.aolcdn.com/dojo/1.3 to point to 
http://o.aolcdn.com/dojo/1.3.1 (where http://o.aolcdn.com/dojo will be different based on the xdDojoPath build option).
