OVERVIEW
WHAT IS THIS DOCUMENT? This document is currently mainly a placeholder, to be filled with commonly asked questions about the docidx markup language and compan- ions, and their answers. Please report any questions (and, if possible, answers) we should consider for this document in the category doctools of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. EXAMPLES
WHERE DO I FIND DOCIDX EXAMPLES? We have no direct examples of documents written using docidx markup. However the doctools processor dtplite does generate keyword indices when processing a set of documents written in doctools markup. The intermediate files use docidx markup and are not deleted when generation completes. These files can therefore serve as examples. dtplite is distributed as part of Tcllib, so to get it you need one of [1] A CVS snapshot of Tcllib. How to retrieve such a snapshot and the tools required for this are described at http://source- forge.net/cvs/?group_id=12883 [2] A Tcllib release archive. They are available at http://sourceforge.net/project/showfiles.php?group_id=12883 BUGS, IDEAS, FEEDBACK This document, will undoubtedly contain bugs and other problems. Please report any such in the category doctools of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].
