2.1 Installation on Windows
Although PP3 runs independently of other programs, it is not
useful when it's alone. It needs two external tools in order to work
properly: TeX and Ghostscript.
You need not know how to use TeX and Ghostscript!
On most Unix/Linux systems TeX and Ghostscript are already installed.
But on Windows, you have to install them yourself. Fortunately this is
not difficult, and both programs may be useful for other purposes, too.
