   all languages in WITH_LANG are processed. WITH_LANG=ALL is
   not supported in manual calls.

   Updates the *.tree files.
   At first, the English file is updated based on the English
   help topic titles as read from the help files. Then, the
   localized tree files are written based on the English tree
   file and the localized help topic titles.

   Requires a valid SO/OOo environment.
