what you have online, is in fact, sufficient to start hw4. You need to figure out yourself what transformations are needed. I would start by comparing the piglet/spiglet grammar side by side, and realize what is going on. Once you understand the differences between the two grammars, you're ready to start.
There are no further handouts or materials. What is on the web-- the grammar and the specification, is all you need.
What is different between p3/p4 is that in the previous projects, we told you exactly how to do XYZ. In future project, you will have to figure things out. If we start to tell you the exact transformations you need, that will take away the analytical process and render the projects useless.
Good luck.
Kevin
