Options

-generate: Specifies that a new browser help volume should be created even if the family files and help volumes on the system have not been modified.
-file basename: Specifies the name of the help volume and any intermediate files generated by dthelpgen. The default name is browser.hv.
-lang: Specifies which language directories to search for help families and help volumes. If the -lang option is set, it takes precedence over the current value of the LANG environment variable.

Note -

If you run dthelpgen while the browser volume is displayed in a help window, you should close the window, then reopen the browser volume.
