Only the initial unique characters of each option are significant. Each option must be followed by an argument of the given type. Boolean "true" and "false" are indicated with "y" and "n" respectively. A boolean option without a value is assumed to be "true". For filename arguments, "-" means either stdin or stdout as appropriate. Each option is described in detail below.
