-# SYNOPSIS
-#
-# AX_CHECK_ZLIB()
-#
-# DESCRIPTION
-#
-# This macro searches for an installed zlib library. If nothing was
-# specified when calling configure, it searches first in /usr/local and
-# then in /usr, /opt/local and /sw. If the --with-zlib=DIR is specified,
-# it will try to find it in DIR/include/zlib.h and DIR/lib/libz.a. If
-# --without-zlib is specified, the library is not searched at all.
-#
-# If either the header file (zlib.h) or the library (libz) is not found,
-# the configuration exits on error, asking for a valid zlib installation
-# directory or --without-zlib.
-#
-# The macro defines the symbol HAVE_LIBZ if the library is found. You
-# should use autoheader to include a definition for this symbol in a
-# config.h file. Sample usage in a C/C++ source is as follows:
-#
-# #ifdef HAVE_LIBZ
-# #include <zlib.h>
-# #endif /* HAVE_LIBZ */
