+#
+# SYNOPSIS
+#
+# AX_LIB_MYSQL([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+# This macro provides tests of availability of MySQL client library
+# of particular version or newer.
+#
+# AX_LIB_MYSQL macro takes only one argument which is optional. If
+# there is no required version passed, then macro does not run
+# version test.
+#
+# The --with-mysql option takes one of three possible values:
+#
+# no - do not check for MySQL client library
+#
+# yes - do check for MySQL library in standard locations
+# (mysql_config should be in the PATH)
+#
+# path - complete path to mysql_config utility, use this option if
+# mysql_config can't be found in the PATH
+#
+# This macro calls:
+#
+# AC_SUBST(MYSQL_CFLAGS)
+# AC_SUBST(MYSQL_LDFLAGS)
+# AC_SUBST(MYSQL_VERSION)
+#
+# And sets:
+#
+# HAVE_MYSQL
+#
