public abstract class VelocityTagSupport

extends org.apache.commons.jelly.TagSupport

Support methods for the Velocity tag library. Currently this is only used to get an instance of the VelocityEngine. For each unique base directory specified, a new VelocityEngine instance is stored in the context (as the author hasn't figured out how to change the resource loader of an already init'd VelocityEngine).
