- * TIFF Library.

- * ZIP (aka Deflate) Compression Support
- *
- * This file is simply an interface to the zlib library written by
- * Jean-loup Gailly and Mark Adler.  You must use version 1.0 or later
- * of the library: this code assumes the 1.0 API and also depends on
- * the ability to write the zlib header multiple times (one per strip)
- * which was not possible with versions prior to 0.95.  Note also that
- * older versions of this codec avoided this bug by suppressing the header
- * entirely.  This means that files written with the old library cannot
- * be read; they should be converted to a different compression scheme
- * and then reconverted.
- *
- * The data format used by the zlib library is described in the files
- * zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available in the
- * directory ftp://ftp.uu.net/pub/archiving/zip/doc.  The library was
- * last found at ftp://ftp.uu.net/pub/archiving/zip/zlib/zlib-0.99.tar.gz.
