Imploded entry decompression for Zip archives (method 6)
--------------------------------------------------------
Key: COMPRESS-115
URL: https://issues.apache.org/jira/browse/COMPRESS-115
Project: Commons Compress
Issue Type: New Feature
Affects Versions: 1.0
Reporter: Emmanuel Bourg
This is a RFE to implement the decompression of zip file entries using the
imploded compression method (aka method 6). This method is found in archives
created with old versions of PKZip. Only the decompression operation is really
useful since this method is less efficient than deflate.
