ZILF is an open-source ZIL compiler, Z-machine assembler, world model, and related tools written by Jesse McGrew. ZILF has been said to stand for either Zork Implementation Language of the Future or The ZIL Implementation You Really, Really Like. It is written in C#, and runs under Windows, or under MacOS or Linux using Mono. It takes ZIL source code and compiles it into Z-machine assembly code, which is then passed to ZAPF to make the final Z-code story file.
