How to create new *.script files for own tools? Assume I want to add own resp. new tools to an existing PEBakery installation. I guess I have to create a corresponding *.script file similar to WinBuilder. But: How do I do this in PEBakery? In WinBuilder there are some Utilties included which let me do this. I miss such utilties in PEBakery. How does it work here? Can I simply copy the *.script files from WinBuilder (=are the *.script files compatible)?
