It looks like I accidentally deleted zlib from the Zope package. (I thought I was deleting it from the Zope3 package, but it ends up it was symlinked to both places. Thus, when I deleted it, I removed it from both places.) Before I revert the checkins and tweak the Zope3 links appropriately, I thought I'd ask if there is any need to distribute zlib with Zope. Is there? Jeremy
