@c Let's use the concept of 'renditions' by Fra@,{c}ois Pinard
@c I extended it by adding a FIXME_FOOTNOTE variable, which controls
@c whether FIXME information should be placed in footnotes or
@c inlined. 

@c ======================================================================
@c This document has three levels of rendition: PUBLISH, DISTRIB or PROOF,
@c as decided by @set symbols. The PUBLISH rendition does not show
@c notes or marks asking for revision. Most users will prefer having more
@c information, even if this information is not fully revised for adequacy,
@c so DISTRIB is the default for distributions. The PROOF rendition
@c show all marks to the point of ugliness, but is nevertheless useful to
@c those working on the manual itself.
@c ======================================================================

@c Set this symbol if you wish FIXMEs to appear in footnotes, instead
@c of being inserted into the text.
@c @set PROOF_FOOTNOTED

@ifclear PUBLISH
@ifclear DISTRIB
@ifclear PROOF
@set DISTRIB
@end ifclear

@ifset PUBLISH
@set RENDITION The book, version

@ifset DISTRIB

@macro WRITEME
@ifclear PUBLISH
@quotation
@emph{This node is to be written.}
@end quotation
@end ifclear
@end macro

@c Output marks for nodes needing revision, but not in PUBLISH rendition.

@macro UNREVISED
@ifclear PUBLISH
@quotation
(@emph{The information in this node may be obsolete or otherwise inaccurate.}
This message will disappear, once this node revised.)
@end quotation
@end ifclear
@end macro

@c Output various FIXME information only in PROOF rendition.
