+ Using Coccinelle on (modified) files
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To apply Coccinelle on a file basis, instead of a directory basis, the
+following command may be used:
+
+    make C=1 CHECK="scripts/coccicheck"
+
+To check only newly edited code, use the value 2 for the C flag, i.e.
+
+    make C=2 CHECK="scripts/coccicheck"
+
+This runs every semantic patch in scripts/coccinelle by default. The
+COCCI variable may additionally be used to only apply a single
+semantic patch as shown in the previous section.
+
+The "chain" mode is the default. You can select another one with the
+MODE variable explained above.
+
+In this mode, there is no information about semantic patches
+displayed, and no commit message proposed.
