  unzip.h

  This header file is used by all of the UnZip source files.  Its contents
  are divided into seven more-or-less separate sections:  predefined macros,
  OS-dependent includes, (mostly) OS-independent defines, typedefs, function 
  prototypes (or "forward declarations," in the case of non-ANSI compilers),
  macros, and global-variable declarations.
