OpenACS Package

A "package" represents a unit of OpenACS/]po[ code that can be separately installed or uninstalled by the OpenACS package manager. For a listing of all available ]project-open[ packages see Packages 

Each package consists of:

• TCL library Files
• AOLServer Dyanmic Pages (ADP) Files
• PostgresSQL Files
• XQL Files
  

The TCL files are responsible for the creation of ADP pages, which the end user sees as they are clicking through ]project-open[.  The PostgresSQL files contain the database tables for information storage and retrieval.  The XQL Files are built as a layer of abstraction on top of the SQL in order to (?).
