* When Chelp is called the help file is loaded from

* BitchX.help and saved. This file is never loaded from disk after this.
|

* Information from the help file is loaded into an array as 0-Topic.
|
||||
* $help() also calls the same routines except this information is loaded
|
||||
* differantly as 1-Topic. this allows us to distingush between them
