+# 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
