Recommended usage of gd1

The most effective usage of gd1 is:

• Write an inputfile
• Until gd1 does what you want him to do:
  • feed gd1 with the inputfile
  • Change the inputfile

If you work with several xterms, this cycle is very fast. Figure 1.1 shows a typical ``desktop`` with three xterms. The upper right xterm is a terminal running an editor to change the inputfile, the lower right xterm is used to feed gd1 with the actual inputfile, and a third xterm is used to run another instance of gd1. This second instance of gd1 is used to look-up the syntax of gd1's commands.

Figure 1.1: Screenshot of a typical desktop when one uses gd1. The xterm in the upper right corner is used to edit the inputfile, the xterm in the lower right is used to feed gd1 with the inputfile, and the long xterm on the right side runs another instance of gd1. This second instance of gd1 is used to look-up the syntax of gd1's command language.
