+ === XMAP & Pipelines ===
+ 
+ Lenya uses Cocoon's XMAP ("sitemap") language and Cocoon pipelines (generators, matchers, selectors, actions, transformers, and serializers) for defining the sequence of events that happens with each request to the server.  It is critical to have a good understanding of XMAP syntax when developing any site using Lenya.

+ === Apache Ant ===
+ 
+ Ant is a tool used most commonly to compile/build Java applications.  But [http://lenya.apache.org/1_2_x/components/tasks/anttask.html Lenya also uses Ant Tasks] to do file system operations (particulary file moves & copies -- see [http://lenya.apache.org/apidocs/1.2/org/apache/lenya/cms/ant/package-summary.html list of Lenya ant tasks]) in an platform-independent way.
+ 
+ === Server-side JavaScript ===
+ 
+ Lenya uses Javascript on the server side to define workflow logic.  It uses a version of Mozilla Rhino, an implementation of the JavaScript language in Java, that has been modified to support [http://wiki.apache.org/cocoon/RhinoWithContinuations Continuations].  If you will be developing a custom workflow you will need a good grasp of this technology.
+ 
+ === XSP ===
+ 
+ XSP, or eXtensible Server Pages, is a Cocoon technology roughly analogous to Java Server Pages, but with a number of key differences.  Lenya uses XSP's to generate an XML stream dynamically rather than by reading an xml file.
+ 
  === JCR ===
   
  The Java Content Repository (JCR) API (JSR 170) defines a standard to access content repositories from Java code, and promises to greatly simplify Java database programming.
