zipfile compression utility.

This package is currently maintained by Santiago Vila

The changes were fairly minimal, and consisted solely of adding
various debian/* files to the distribution.

       explicit permission of Info-ZIP.  Such altered versions are further
       prohibited from misrepresentative use of the Zip-Bugs or Info-ZIP

       will provide support for the altered versions.
