+#
+#   Look for OpenSSL in a number of default spots, or in a user-selected

+#
+#   This macro sets OPENSSL_INCLUDES such that source files should use the

+# ===========================================================================
+#
+# SYNOPSIS
+#
+#   AX_CHECK_ZLIB([action-if-found], [action-if-not-found])
+#
+# 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,
+#   shell commands 'action-if-not-found' is run. If 'action-if-not-found' is
+#   not specified, the configuration exits on error, asking for a valid zlib
+#   installation directory or --without-zlib.
+#
+#   If both header file and library are found, shell commands
+#   'action-if-found' is run. If 'action-if-found' is not specified, the
+#   default action appends '-I${ZLIB_HOME}/include' to CPFLAGS, appends
+#   '-L$ZLIB_HOME}/lib' to LDFLAGS, prepends '-lz' to LIBS, and calls
+#   AC_DEFINE(HAVE_LIBZ). 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 */
