+ <summary>Client API for the curriculum request system at creq.unl.edu
+</summary>
+ <description>
+This project provides a simple API for the course data within the creq system
+built by Tim Steiner.
+
+This project requires the UNL_Autoload package, and optionally Cache_Lite for
+caching data from the creq system.
+
+Currently data is cached on the local system in /tmp/cache_* files and stored
+for one week.
+
+See the docs/examples/ directory for examples.
+
+For information on the XML format, see the XSD -
