1687 <para>
1688 If you're working on a recipe that pulls from an external Source Code Manager (SCM), it
1689 is possible to have the OpenEmbedded build system notice new changes added to the
1690 SCM and then build the package that depends on them using the latest version.
1691 This only works for SCMs from which it is possible to get a sensible revision number for changes.

1696 To enable this behavior, simply add the following to the <filename>local.conf</filename>

1703 is the name of the package for which you want to enable automatic source
1704 revision updating.
