Working since many years on various data streams I always wanted to have a tool that does the tedious work of analyzing the files automatically. Sometimes I got customer files where the format was unknown, so I wanted to start with some assumptions about the structure and test if these work out for the whole file. Even more important, I wanted to check if the assumptions work even for other files of the same type.
Since I work on a Mac and liked to learn more about Cocoa programming, this was the perfect chance to invest my leisure time for this project.
If you create grammar files for other formats, please forward them to me so I can provide them for other users :)
I hope it's as useful for you as it's fun to develop it!
