     NAME
          dtsdlfile - CDE runtime help volume files

     DESCRIPTION
          Semantic Delivery Language (sdl) files are used for
          presenting online information or application specific
          contextual help information in CDE.  They are refered to as
          Help Volumes, and contain the equivalent of a runtime
          version of the original, authored help information.  Help
          Volumes can be viewed via one of the two CDE help dialog
          widgets provided as part of the CDE Development Environment.

        File Generation
          Refer to the dthelptag(1) man page for detailed information
          on the creation of *.sdl files within CDE.

     ENVIRONMENT VARIABLES
          The CDE Help system uses two environment variables for
          locating Help volumes and Family files within the desktop
          environment:

             DTHELPSEARCHPATH
                            System search path environment variable
                            for locating Help volumes on local and/or
                            remote nfs mounted systems.

             DTHELPUSERSEARCHPATH
                            Users search path environment variable for
                            locating user specific Help volumes on
                            local and/or remote nfs mounted systems.

          The environment variables contain colon-separated lists of
          directory paths.  Each directory path can contain
          environment variable names as well as special field
          descriptors that are expanded at runtime.

          Field descriptors consist of a % followed by a single
          character.  Field descriptors and their substitution values
          are:

             %H             This value is replaced with the current
                            volume or Family name being searched for.

             %L             Replaced with the current value of the
                            LANG environment variable.

             %%             Replaced with a single %.

          The default value for DTHELPUSERSEARCHPATH is:

          $HOME/.dt/help/$DTUSERSESSION/%H:
          $HOME/.dt/help/$DTUSERSESSION/%H.sdl:
          $HOME/.dt/help/$DTUSERSESSION/%H.hv:
          $HOME/.dt/help/%H:
          $HOME/.dt/help/%H.sdl:
          $HOME/.dt/help/%H.hv

          The DTHELPUSERSEARCH is first searched for the requested
          volume.  If the volume is not found, the DTHELPSEARCHPATH
          value is searched.

          The default value for DTHELPSEARCHPATH path is:

          /etc/dt/appconfig/help/%L/%H:
          /etc/dt/appconfig/help/%L/%H.sdl:
          /etc/dt/appconfig/help/%L/%H.hv:
          /etc/dt/appconfig/help/C/%H:
          /etc/dt/appconfig/help/C/%H.sdl:
          /etc/dt/appconfig/help/C/%H.hv:
          /usr/dt/appconfig/help/%L/%H:
          /usr/dt/appconfig/help/%L/%H.sdl:
          /usr/dt/appconfig/help/%L/%H.hv:
          /usr/dt/appconfig/help/C/%H:
          /usr/dt/appconfig/help/C/%H.sdl:
          /usr/dt/appconfig/help/C/%H.hv
