-/* cmCommandArgumentsHelper, cmCommandArgumentGroup and cmCommandArgument (i.e.
-its derived classes cmCAXXX can be used to simplify the processing of
-arguments to cmake commands. Maybe they can also be used to generate
-documentation.
-
-For every argument supported by a command one cmCommandArgument is created
-and added to cmCommandArgumentsHelper. cmCommand has a cmCommandArgumentsHelper
-as member variable so this should be used.
-
-The order of the arguments is defined using the Follows(arg) method. It says
-that this argument follows immediateley the given argument. It can be used
-with multiple arguments if the argument can follow after different arguments.
-
-Arguments can be arranged in groups using cmCommandArgumentGroup. Every
-member of a group can follow any other member of the group. These groups
-can also be used to define the order.
-
-Once all arguments and groups are set up, cmCommandArgumentsHelper::Parse()
-is called and afterwards the values of the arguments can be evaluated.
-
-For an example see cmExportCommand.cxx.
