To specify which topic file to display when Eclipse Help opens:
[EclipseHelpOptions]
; TocTopic = name of opening topic file (required)
TocTopic = startingtopic.htm
The default starting topic is the first HTML file listed in the generated contents. That is, if you do not include any setting for TocTopic, DITA2Go generates an entry of the following form in toc.xml:
<toc label="Title of your Help
system" topic="firsttopiclisted.htm">
When an explicit file is named as a topic attribute, Eclipse does not generate a default help page. To allow Eclipse (at least later versions) to generate a default help page, you can avoid specifying an opening topic by giving TocTopic an empty value:
[EclipseHelpOptions]
TocTopic =
When you specify an empty value, DITA2Go omits the topic attribute and generates an entry of the following form in toc.xml:
<toc label="Title of your Help
system">
In this case, Eclipse generates a default opening page with the following content:
Title of your Help system
