+zlib 0.71 is a beta version of a general purpose compression library.
+
+The data format used by the zlib library is described in the
+file zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
+in ftp.uu.net:/pub/archiving/zip/doc.
+
+All functions of the compression library are documented in the file
+zlib.h. A usage example of the library is given in the file example.c
+which also tests that the library is working correctly.
+To compile all files and run the test program, just type: make test
+
+The changes made in version 0.71 are documented in the file ChangeLog.
+The main changes since 0.5 are:
+- added full inflate support
+- added minigzip.c
+- added gzdopen to reopen a file descriptor as gzFile
+- added transparent reading of non-gziped files in gzread.
+- fix some MSDOS problems. example and minigzip now work on MSDOS.
+- Simplified the crc32() interface. The pre- and post-conditioning
+  (one's complement) is now done inside crc32(). WARNING: this is
+  incompatible with previous versions; see zlib.h for the new usage.
+
+On MSDOS, this version works in large and small model with MSC; in
+small model only with TurboC (bug being investigated). For both
+compilers, small model compression works only for small values of
+MEM_LEVEL and WBITS (see zutil.h), and requires -DUSE_CALLOC.
