  unzip.h (new)

  This header file contains the public macros and typedefs required by
  both the UnZip sources and by any application using the UnZip API.  If
  UNZIP_INTERNAL is defined, it includes unzpriv.h (containing includes,
  prototypes and extern variables used by the actual UnZip sources).
