Is there a document describing cstyle rules?

I can read through the cstyle script and deduce what it will complain about, but I was hoping to find a clear concise document spelling out the rules of cstyle in English.

For example, cstyle.pl can be found here: http://cvs.opensolaris.开发者_StackOverfloworg/source/xref/onnv/onnv-gate/usr/src/tools/scripts/cstyle.pl

From the community page for the ONNV project that script was hosted at, I found this Cstyle guide.
