     This man page only documents command line options and environment
     variables.  The full package and documentation are available at

     Command line options:

              Text file defining a surface. If omitted, you will be prompted.

              "-a-" to deactivate autoconversion.

     -d       Begin with parser debugging on (equivalent to "debug" runtime
              command).  Beware of copious output.

     -e       Echo stdin to stdout; meant for testing piped input.

     -m       Begin with memory debugging on (equivalent to "memdebug" runtime
              command).  Beware of copious output.

     -pN      Run with N concurrent processes.

     -q       Convert to named quantities at start (equivalent to
              "convert_to_quantities" runtime command).

     -Q       Suppress echoing of "read" section of datafile, and other files
              read in.

     -w       Exit immediately after any warning or error message; meant for
              batch runs.

     -x       Exit immediately after any error message; meant for batch runs.

     -y       Break to user prompt after any warning message.
