I wrote this bash script to change DPRINTK and other non-standard debugging to a form that can be added as a menu option.
it does not add the kconfig options, I'm not sure how to put that in this script. It appends to a file ../kcs what Kconfig file it thinks that should be edited, and the CONFIG_*_DEBUG option to add there, and the source file in which changes were made.
