If you like, you can include useful descriptive information in the manifest file. For example, you can describe each package by a section that begins with its relative path name, including the trailing slash. Then, you can specify, for example, version details:
Main-Class: MovieApplicationTestor Class-Path: Entertainment.jar Name: application/ Specification-Title: "Application specifications" Specification-Version: "3.141" Specification-Vendor: "XYZ, Inc." Implementation-Title: "Application implementation" Implementation-Version: "Build 2.718" Implementation-Vendor: "XYZ, Inc." Name: model ... Name: view ...
