I am not sure about this. The gain is really only on systems with large
clusters, and that means Windows VFAT16, where small clusters are 4Kb and
clusters can be 32Kb (and are on a > 1Gb disc).
The other issue is licensing. I compiled unzip for Win32 and followed the
minimal allowed distribution as part of the binary distribution. On
source platforms the use of unzip would be optional, but with binary
distributions you would need to ensure unzip is available.
Is there any interest in having this on Unix/Linux platforms? If so I can
very easily change the source code to search zip files if present.
