485/*
486 Notes: ShowHelp uses section ids for displaying particular topics,
487 but you might want to use a unique keyword to display a topic, instead.
488
489 Section ids are specified as follows for the different formats.
490
491 WinHelp
492
493 The [MAP] section specifies the topic to integer id mapping, e.g.
494
495 [MAP]
496 #define intro 100
497 #define functions 1
498 #define classes 2
499 #define about 3
500
501 The identifier name corresponds to the label used for that topic.
502 You could also put these in a .h file and #include it in both the MAP
503 section and your C++ source.
504
505 Note that Tex2RTF doesn't currently generate the MAP section automatically.
506
507 MS HTML Help
508
509 The [MAP] section specifies the HTML filename root to integer id mapping, e.g.
510
511 [MAP]
512 #define doc1 100
513 #define doc3 1
514 #define doc2 2
515 #define doc4 3
516
517 The identifier name corresponds to the HTML filename used for that topic.
518 You could also put these in a .h file and #include it in both the MAP
519 section and your C++ source.
520
521 Note that Tex2RTF doesn't currently generate the MAP section automatically.
522
523 Simple wxHTML Help and External HTML Help
524
525 A wxhelp.map file is used, for example:
526
527 0 wx.htm ; wxWindows: Help index; additional keywords like overview
528 1 wx204.htm ; wxWindows Function Reference
529 2 wx34.htm ; wxWindows Class Reference
530
531 Note that Tex2RTF doesn't currently generate the MAP section automatically.
532
533 Advanced HTML Help
534
535 An extension to the .hhc file format is used, specifying a new parameter
536 with name="ID":
537
538 <OBJECT type="text/sitemap">
539 <param name="Local" value="doc2.htm#classes">
540 <param name="Name" value="Classes">
541 <param name="ID" value=2>
542 </OBJECT>
543
544 Again, this is not generated automatically by Tex2RTF, though it could
545 be added quite easily.
546
547 Unfortunately adding the ID parameters appears to interfere with MS HTML Help,
548 so you should not try to compile a .chm file from a .hhc file with
549 this extension, or the contents will be messed up.
