-dnl Available from the GNU Autoconf Macro Archive at:
-dnl http://www.gnu.org/software/ac-archive/htmldoc/check_zlib.html
+dnl @synopsis CHECK_ZLIB()
 dnl
+dnl This macro searches for an installed zlib library. If nothing was
+dnl specified when calling configure, it searches first in /usr/local
+dnl and then in /usr. If the --with-zlib=DIR is specified, it will try
+dnl to find it in DIR/include/zlib.h and DIR/lib/libz.a. If
+dnl --without-zlib is specified, the library is not searched at all.
+dnl
+dnl If either the header file (zlib.h) or the library (libz) is not
+dnl found, the configuration exits on error, asking for a valid zlib
+dnl installation directory or --without-zlib.
+dnl
+dnl The macro defines the symbol HAVE_LIBZ if the library is found. You
+dnl should use autoheader to include a definition for this symbol in a
+dnl config.h file. Sample usage in a C/C++ source is as follows:
+dnl
+dnl   #ifdef HAVE_LIBZ
+dnl   #include <zlib.h>
+dnl   #endif /* HAVE_LIBZ */
