+ Overview / Quick Start
+There are two ways to use Coccinelle with the Linux kernel.
+1) Coccinelle can be used like sparse (see Documentation/sparse.txt):
+ make C=1 CHECK="scripts/coccicheck"
+ make C=2 CHECK="scripts/coccicheck"
+2) Coccinelle can be used via a build target in the kernel's Makefile:
+ make coccicheck
+There are a number of optional parameters that can be used with the build target.
+ make coccicheck MODE={patch,report,context,org} COCCI=? M=?
+ Determines what mode cocci operates in. If no mode is specified
+ then cocci will default to 'chain' mode which will run for each
+ available mode (patch, report, context, org).
+ Process a specific .cocci SmPL script. If this is not set then
+ process all scripts under scripts/coccinelle/
+ Limit cocci to a subset of directories. This is very similar to the
+ way the build system works when building modules.
