+description = [[
+Discovers Microsoft SQL servers in the same broadcast domain.
+
+SQL Server credentials required: No (will not benefit from
+<code>mssql.username</code> & <code>mssql.password</code>).
+
+The script attempts to discover SQL Server instances in the same broadcast
+domain. Any instances found are stored in the Nmap registry for use by any
+other ms-sql-* scripts that are run in the same scan.
+
+In contrast to the <code>ms-sql-discover</code> script, the broadcast version
+will use a broadcast method rather than targeting individual hosts. However, the
+broadcast version will only use the SQL Server Browser service discovery method.
