NAME

       Padre::Help - Padre Help Provider API

DESCRIPTION

       The "Padre::Help" class provides a base class, default implementation and API
       documentation for help provision support in Padre.

       In order to setup a help system for a document type called "XYZ" one has to do the
       following: Create a module called "Padre::Help::XYZ" that subclasses the "Padre::Help"
       module and override 3 methods: "help_init", "help_list" and "help_render".

       In the class representing the Document ("Padre::Document::XYZ") one should override the
       "get_help_provider" method and return an object of the help provide module.  In our case
       it should contain

               require Padre::Help::XYZ;
               return Padre::Help::XYZ->new;

       (TO DO: Maybe it should only return the name of the module)

       The "help_init" method is called by the new method of "Padre::Help" once for every
       document of "XYZ" kind. (TO DO: maybe it should be only once for every document type, and
       not once for every document of that type).

       "help_list" should return a reference to an array holding the possible strings the system
       can provide help for.

       "help_render" is called by one of the keywords, it should return the HTML to be displayed
       as help and another string which is the location of the help. Usually a path to a file
       that will be used in the title of the window.
