 Bionic comes with a processed set of all of the uapi Linux kernel headers that
 can safely be included by userland applications and libraries.
 
 These clean headers are automatically generated by several scripts located

 After running lunch, run this command to import the headers into the android
 source tree:
-
+```
   bionic/libc/kernel/tools/generate_uapi_headers.sh --use-kernel-dir kernel_src

 Next, run this command to copy the parsed files to bionic/libc/kernel/uapi:
-

 Finally, run this command to regenerate the syscalls list:

 After this, you will need to build/test the tree to make sure that these
 changes do not introduce any errors.
