### 20.11 Merging JavaHelp or Oracle Help systems

JavaHelp and Oracle Help for Java support limited merging of helpsets. You list subprojects in the main project helpset; the subproject information is appended to the main project information. In the contents, subprojects are listed one after the other, after the main project, and each subproject has to begin at the top level. Index entries for each subproject are appended to those for the main project, for JavaHelp; index merging is implemented somewhat better for Oracle Help.

To specify that helpsets are to be merged:

    [JavaHelpOptions] or [OracleHelpOptions]
    ; UseSubHelpSets = No (default) or Yes (requires [HelpMergePaths])
    UseSubHelpSets = Yes

You must specify the path to the run-time location of each subproject helpset, relative to the main project helpset. For example:

    [HelpMergePaths]
    ; subproject name = path to its files during use (not construction)
    mysub = ../mysub/

Only the path is used, not the helpset name.
