DESCRIPTIONThe "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.
