  source/        subdirectory containing all sources:
                  a) Zip specific code
    extrafld.c      contains all code related to the mac extra field
    extrafld.h
    macglob.h

    pathname.c      functions for handling MacOS HFS path- /filenames
    pathname.h

The new ZpPrj.hqx project file should be "un-BinHex'ed" into ZpPrj,
which builds the following targets:
        - Zip Lib (68K)   -> static library 68k
        - Zip Lib (PPC)   -> static library PPC
        - Zip Sioux (68K) -> MW Sioux standalone App, good for debugging
        - Zip Sioux (PPC) -> MW Sioux standalone App, good for debugging


The resource files and the compiler project files are in BinHex form because
they contain Macintosh resource forks.  The resource info cannot be
maintained when handling (e.g. repacking) the master source collection on
non-Macintosh systems.  The BinHex form is the traditional way for
transferring such files via non-Macintosh systems.
It's also the safest since it uses only printable characters.  The ".hqx"
files must be converted with StuffitExpander or BinHex 4.0 (or equivalent)
on a Macintosh system before using them.
