+
+Extract source of recipe
+========================
+
+Use the ``devtool extract`` command to extract the source of a recipe to the
+directory specified. The extract command can extract the source of a recipe
+with patches applied to a directory on the system, not constrained to the
+devtool workspace.
+
+To extract the source of a recipe use the this command::
+
+        $ devtool extract recipe /path/to/extract/location
+
+In contrary to the ``devtool modify`` command this extracted copy will have no
+impact on builds and can not be integrated back in to recipes by using devtool.
+
+.. _devtool-sync-extracted-source-of-recipe:
+
+Sync extracted source of recipe
+===============================
+
+Use the ``devtool sync`` command to synchronize a previously extracted source
+tree of a recipe with the latest status of the recipe.
+
+To synchronize the extracted source tree of a recipe use this command::
+
+    $ devtool sync recipe /path/to/existing/extract/location
+
+.. note::
+
+   The synchronization of ``devtool sync`` could remove work you have in your
+   checked out tree as it will set the new head of the devtool branch to the
+   latest commit specified by the recipe. The previous devtool branch will be
+   copied to the devtool.bak branch
