-- Documentation can be woven into a source file. This script can generates
-- a file with the documentation and source fragments properly tagged. The
-- documentation is included as comment:
--
-- %D ......  some kind of documentation
-- %M ......  macros needed for documenation
-- %S B       begin skipping
-- %S E       end skipping
--
-- The generated file is structured as:
--
-- \starttypen
-- \startmodule[type=suffix]
-- \startdocumentation
-- \stopdocumentation
-- \startdefinition
-- \stopdefinition
-- \stopmodule
-- \stoptypen
--
-- Macro definitions specific to the documentation are not surrounded by
-- start-stop commands. The suffix specification can be overruled at runtime,
-- but defaults to the file extension. This specification can be used for language
-- depended verbatim typesetting.
--
-- In the mkiv variant we filter the \module settings so that we don't have
-- to mess with global document settings.
