The user is able to start Wolfgang after Java was installed and congured successfully.
The tool is showing its startup-screen directly after the start. This rst screen is going to
be discussed in the following chapter.

The startup-screen oers the possibility to choose between two dierent net types, or to
open an existing net. Users can either create a place/transition net (P/T-Net) by clicking
the left button or start to construct a colored Petri net (CPN) by selecting the one located
in the middle. An open-dialog appears by clicking the “open” button on the right side
of the startup-screen. Subsequently it is possible to open an existing P/T-Net or CPN in
PNML format by selecting a net and clicking on the button “load PNML”.

After one option has been chosen, the startup-screen disappears and the home-screen
shows up.
