Ghostscript (gs) is a programming language similar to Adobe Systems' PostScript (tm) language, which is in turn similar to Forth. Gs reads files in sequence and executes them as Ghostscript programs. After doing this, it reads further input from the standard input stream (normally the keyboard). Each line is interpreted separately. To exit from the interpreter, enter the `quit' command. The interpreter also exits gracefully if it encounters end-of-file. Typing the interrupt character (e.g. Control-C) is also safe.
