Syntax of the FM Language

FilterMeister actually supports several plug-in filter design languages, including

Adobe's original Filter Factory (FF) language,
Mario Klingemann's Filter Factory Wizard (FFW),
the extended Filter Factory Plus (FFP) language, and
the all-encompassing FilterMeister Language (FML)

As such, the syntax of the total union of all languages is rather complex, but may be more readily understood by examining the syntax of each component language individually.
