As part of scene-serialization, we need a module encapsulating a library for creating and reading .zip files. Seemingly Info-ZIP seems most suited. Info-ZIP is (at least in part) used by WinZip and has a permissive license: http://infozip.sourceforge.net/license.html
A module should be created for the pure purpose of creating and reading .zip files. Info-ZIP is just one option, more shoud be considered.
