To provide a label to be displayed as the “book” level of the helpset in the Eclipse Help Contents pane:
[EclipseHelpOptions] ; TocLabel = text that appears in the Eclipse Help Contents pane TocLabel = Title for your Eclipse Help system
The default value of TocLabel is the value supplied for PluginName; see §21.3.1 Specifying a Java manifest file for Eclipse Help. This is not usually what you want.
