-- A parameter is defined as a whitespace bounded string, not beginning
-- with a slash. (But see note under FILES_OR_WILDCARD).

-- A required file or directory parameter

-- An optional file or directory parameter

-- An unlimited number of whitespace separate file or directory
-- parameters including wildcard specifications.

-- An unlimited number of whitespace separated parameters that are

-- Describes the allowable types of parameters.
-- Params (1) is the type of the first parameter, etc.
-- An empty parameter array means this command takes no parameters.
