Jar files are just zip files with a particular interpretation for certain files in the zip under the META-INF/ directory. So we can read and write them using the standard zipfile module.

Attributes: main_section: a dict representing the main (first) section of the manifest. Each key is a string that is an attribute, such as 'Manifest-Version', and the corresponding value is a string that is the value of the attribute, such as '1.0'. sections: a dict representing the other sections of the manifest. Each key is a string that is the value of the 'Name' attribute for the section, and the corresponding value is a dict like the main_section one, for the other attributes. c ||_||_y)N) main_sectionsections)selfrrs r__init__zManifest.__init__;s$DDMrN)r r r __doc__rr rrrr-s  rrctj|5} |jtj d}t ||cdddS#t $r YdddywxYw#1swYyxYw)aRead and parse the manifest out of the given jar.
