function page_example_help

Implements hook_help().

Through hook_help(), a module can make documentation available to the user for the module as a whole or for specific paths. Where the help appears depends on the $path specified.

In the first example below, the help text will appear on the simple page defined in hook_menu below in the region designated for help text.

In the second example, the text will be available through the module page as a link beside the module or on the admin help page (admin/help) in the list of help topics using the name of the module. To specify help in the admin section use the module name in the path as in the second case below.
