You can achieve similar results with zip like so:

   pkzip -e0 -r -p djdev201.ze0 bin\*.* include\*.* lib\*.* zoneinfo\*.*
   pkzip -ex djdev201.zip djdev201.ze0

The -e0 flags tells PKZIP to make an uncompressed archive which is then 
compressed into the final zip.

The main reason in using Zip is its wide availability, on both DOS and
Unix platforms.  Most other archivers aren't available so widely on one or
the other of these platforms.
