Yes, except if the shell can't find the man file (or it is invalid), then the shell should simply execute the .efi and let it handle the command line (regardless of EFI_HII_PACKAGE_LIST_PROTOCOL_GUID, etc.).

But it means distributing a UEFI shell application not only means distributing a .EFI file but also distributing a .MAN file. If the text formatted .MAN file is corrupted (edited by user by mistake), or is missing (deleted by user by mistake), no help will be shown to user. So I propose to embedded the help message inside the .EFI file in a PE resource section and the algorithm to find help for a standalone application is as following. Search command.man file for valid help content If command.man exists and help content is valid: Display the help Else: Load the command.efi (do not start it) Check whether the ImageHandle has EFI_HII_PACKAGE_LIST_PROTOCOL_GUID installed Check all strings in the HII packages to find a string which follows spec defined help format If the string exists: Display the help Else: Show "no Help" Any comments, concerns?
