Hi all,

What is the usage of this directory? It has a file called MANIFEST.INF. From what I read online, it says that this file has information on classes in the jar files. But what kinda information is it?

It contains meta information about the library e.g. when you sign a jar it will have integrity details of each and every file inside the jar that way it can be verified.
It is sorta covered in the JavaRanch Style Guide.
