/**
* EShellModuleInfo:
* @name: The name of the module. Also becomes the name of
* the corresponding #EShellView subclass that the
* module will register.
* @aliases: Colon-separated list of aliases that can be used
* when referring to a module by name.
* @schemes: Colon-separated list of URI schemes. The #EShell
* will forward command-line URIs to the appropriate
* module based on this list.
* @sort_order: Used to determine the order of modules listed in
* the main menu and in the switcher. See
* e_shell_module_compare().
* @start: Callback for notifying the module to begin loading data
* and running background tasks. This is called the first
* time the corresponding shell view class is instantiated.
* It allows the module to delay initialization steps that
* consume significant resources until they are actually
* needed.
* @is_busy: Callback for querying whether the module has
* operations in progress that cannot be cancelled
* or finished immediately. Returning %TRUE prevents
* the application from shutting down.
* @shutdown: Callback for notifying the module to begin
* shutting down. Returning %FALSE indicates there
* are still unfinished operations and the #EShell
* should check back shortly.
* @migrate: Callback for notifying the module to migrate data and
* settings from the given version. Returns %TRUE if the
* migration was successful or if no action was necessary.
* Returns %FALSE and sets a #GError if the migration failed.
*
* Provides basic information about an #EShellModule instance. Shell
* modules should pass this structure to e_shell_module_set_info() in
* their "e_shell_module_init" functions.
