               Set default hardcopy device. See xmgrace -version for a list of
               supported devices.

          -install

     RESOURCES
     settings.
          When run in the GUI mode, the interface is a subject to X resource
               Please refer to the User's Guide for a list of important ones.

     ENVIRONMENT
          GRACE_HOME
               Specifies the directory where the Grace docs and libs are stored.
               Default is /usr/local/grace

          GRACE_HELPVIEWER
               The shell command to run an HTML viewer for on-line browsing of
               the help documents. Must include at least one instance of "%s"
               which will be replaced with the actual URL by Grace. Default is
               mozilla %s

          GRACE_EDITOR
               Specifies the editor which is used to edit sets. Default is xterm
               -e vi

          GRACE_PRINT_CMD
               The print command.

          GRACE_FFTW_RAM_WISDOM
               and GRACE_FFTW_WISDOM_FILE A flag (0 or 1) and a file name which
               determine whether a FFT should use `wisdom' when using the FFTW
               libraries.

     FILES
          In many cases, when Grace needs to access a file given with a relative
          pathname, it searches for the file along the following path:
           ./pathname:./.grace/pathname:~/.grace/pathname:$GRACE_HOME/pathname

          The following files are of a special importance:

          gracerc - init file loaded upon start up.
