hook_help
function hook_help
hook_help($path, $arg)
Provide online user help.
By implementing hook_help(), a module can make documentation available to the user for the module as a whole, or for specific paths. Help for developers should usually be provided via function header comments in the code, or in special API example files.
The page-specific help information provided by this hook appears as a system help block on that page. The module overview help information is displayed by the Help module. It can be accessed from the page at admin/help or from the Modules page.
For detailed usage examples of:
- Module overview help, see node_h
