 """Creates a TOC file from a Java jar.
 
 The TOC file contains the non-package API of the jar. This includes all
 public/protected classes/functions/members and the values of static final
 variables. Some other information (major/minor javac version) is also included.
 
 This TOC file then can be used to determine if a dependent library should be
 rebuilt when this jar changes. I.e. any change to the jar that would require a
 rebuild, will have a corresponding change in the TOC file.
