+Customizing packages
+~~~~~~~~~~~~~~~~~~~~
+
+It is sometimes useful to apply 'extra' patches to packages - over and
+above those provided in Buildroot. This might be used to support custom
+features in a project, for example, or when working on a new architecture.
+
+The +BR2_EXTRA_PACKAGE_PATCH_DIRS+ configuration file option can be
+used to specify a set of extra package patch directories. The option
+should be set to a space-separated list of directories containing the
+extra package patches. Note that any extra patches for a package
+will be applied *after* the Buildroot patch set for the package.
