 150 Options:
 151
 152   -2, --2d
 153     Create 2D plot instead of 3D. Bigger window by default in gnuplot,
 154     and it’s faster when plotting lots of data.
 155   -h, --help
 156     Show this help.
 157   -k, --keep-files
 158     Don’t remove temporary files after program execution.
 159   -l X, --label-file X
 160     Use X as label file.
 161     Default: $Std{'label-file'}
 162   -t, --time
 163     Use time as Z axis instead of elevation.
 164   -v, --verbose
 165     Increase level of verbosity. Can be repeated.
 166   -w X, --with X
 167     Use line type X:
 168       d  - dots
 169       l  - lines
 170       p  - points
 171       lp - lines with points
 172       Default: $Std{'with'}
 173   --version
 174     Print version information.
 175   --debug
 176     Print debugging messages.
