  * Parse 'helix' XML representation

  * 
+ * A bit of history: "Helix Code" was the name of the company that
+ * wrote Red Carpet. The company was later renamed to Ximian.
+ * The Red Carpet solver was merged into the ZYPP project, the
+ * library used both by ZENworks and YaST for package management.
+ * Red Carpet came with solver testcases in it's own repository
+ * format, the 'helix' format.
