dwww-build builds the index lists of all available documents (manual pages, Info files, and so on); it
should be run whenever documentation is installed or removed. dwww(7) does not work unless dwww-build
has been run at least once; when the package is installed, it is run automatically. The default dwww
installation creates a /etc/cron.daily/dwww, which automatically updates the pages each day.
The html-directory argument specifies the directory where all the dwww HTML files will be stored. No
other files should be stored there. If --default is used, the files are generated in dwww subdirectory
of the directory specified in the DWWW_DOCROOTDIR variable in the /etc/dwww/dwww.conf file. (Default is
/var/www/dwww.)
