The plug-in information file must be stored in its containing archive under the path META-INF/PLUG-IN.XML. In addition it should validate under the plug-in data type declaration (http://cs.oberlin.edu/~jwalker/plug-in/fileFormat/plug-in.dtd). An example XML plug-in information file is available at http://cs.oberlin.edu/~jwalker/plug-in/fileFormat/PLUG-IN.XML.

1. The major, minor, patch and release elements must contain a decimal integer
2. The url element should contain a valid fully-qualified URL (i.e. use "http://" etc.)
3. The class element should contain the package and class name of the plug-in class

Package names should be separated with a dot, and the class name should not have .class at the end
