Perl/Tk saves your favourite tools

In this tutorial you will get a brief introduction to Perl/Tk. The basic mechanisms are discussed, and a few sample programs are discussed in detail.

Then, I will show ways how to link Perl/Tk programs to existing software. In most cases, it is extremely simple to produce a small graphical interface around a text-based tool. So: you do not have to throw away your old, favourite tools; just learn Perl/Tk.

To be able to understand the examples, you have to be familiar with a bit deeper concepts of Perl, like references, object orientation, and ties. We start with freshing up our memory on how these work, but only very superficial.
