I thought someone a while back had indicated a semi-standard wrapper
for zlib zip access in Cocoa. I might be misremembering.
Nitpicking. The CRC16 or more probably CRC32 are included in the zip
spec's I think and have nothing to do with MacBinary. That might be
added if you were supporting Classical era resource forks. For
example a 3rd party shareware package called ZipIt used to encode the
file signature meta information and resource fork data using
MacBinary in the user field of the zip file header.
I did a classical zlib port for java that supported the ZipIt type
files.
