Language.JVM.JarReader

Description

A quick-n-dirty reader for JAR files. MANY keep-it-simple concessions have been made regarding the zip structure of jars (e.g. no ZIP64, Deflate-type compression only, etc., etc.). Please don't mistake this module for any kind of fully-fledged unzip implementation!

Info on the zip file format can be found at: http://www.pkware.com/documents/casestudies/APPNOTE.TXT
