473 /*
474 Notes: ShowHelp uses section ids for displaying particular topics,
475 but you might want to use a unique keyword to display a topic, instead.
476
477 Section ids are specified as follows for the different formats.
478
479 WinHelp
480
481 The [MAP] section specifies the topic to integer id mapping, e.g.
482
483 [MAP]
484 #define intro 100
485 #define functions 1
486 #define classes 2
487 #define about 3
488
489 The identifier name corresponds to the label used for that topic.
490 You could also put these in a .h file and #include it in both the MAP
491 section and your C++ source.
492
493 Note that Tex2RTF doesn't currently generate the MAP section automatically.
494
495 MS HTML Help
496
497 The [MAP] section specifies the HTML filename root to integer id mapping, e.g.
498
499 [MAP]
500 #define doc1 100
501 #define doc3 1
502 #define doc2 2
503 #define doc4 3
504
505 The identifier name corresponds to the HTML filename used for that topic.
506 You could also put these in a .h file and #include it in both the MAP
507 section and your C++ source.
508
509 Note that Tex2RTF doesn't currently generate the MAP section automatically.
510
511 Simple wxHTML Help and External HTML Help
512
513 A wxhelp.map file is used, for example:
514
515 0 wx.htm ; wxWindows: Help index; additional keywords like overview
516 1 wx204.htm ; wxWindows Function Reference
517 2 wx34.htm ; wxWindows Class Reference
518
519 Note that Tex2RTF doesn't currently generate the MAP section automatically.
520
521 Advanced HTML Help
522
523 An extension to the .hhc file format is used, specifying a new parameter
524 with name="ID":
525
526 <OBJECT type="text/sitemap">
527 <param name="Local" value="doc2.htm#classes">
528 <param name="Name" value="Classes">
529 <param name="ID" value=2>
530 </OBJECT>
531
532 Again, this is not generated automatically by Tex2RTF, though it could
533 be added quite easily.
534
535 Unfortunately adding the ID parameters appears to interfere with MS HTML Help,
536 so you should not try to compile a .chm file from a .hhc file with
537 this extension, or the contents will be messed up.
