This archive supplies the copyrighted source for the unreduce
algorithm used in some early beta versions of PKZIP 2.0 and
described in PKWARE's appnote.txt.

As of UnZip 5.42, this source has been removed from Info-ZIP's
UnZip source distribution because of its conflicting copyright.
There are no plans to ever rewrite this code from scratch,
because the unreduce algorithm was never used in the "real" world.

If you really need an UnZip version with support for reduced archive
entries, you have to compile a customized binary yourself:
 - get the source file "unreduce_full.c" (supplied in the Zip
   archive "unreduce_full.zip" together with this README file)
 - rename "unreduce_full.c" to "unreduce.c" and paste it over the
   crippled "unreduce.c" source file of the UnZip source distribution.
 - compile a customized UnZip binary with the option USE_SMITH_CODE
   enabled. In most supported environments, you may define the macro
      LOCAL_UNZIP=-DUSE_SMITH_CODE
   on the command line of the make command, or define an environment
   variable LOCAL_UNZIP, containing the definition of the preprocessor
   macro USE_SMITH_CODE.
