2.21.74 version

The version command lists the version of gnuplot being run, its last modification date, the copyright holders, and email addresses for the FAQ, the gnuplot-info mailing list, and reporting bugs–in short, the information listed on the screen when the program is invoked interactively.

Syntax:

      show version {long}

When the `long` option is given, it also lists the operating system, the compilation options used when `gnuplot` was installed, the location of the help file, and (again) the useful email addresses.
