From 80b810b276cf89587cdaa103e39027813b1be46c Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Fri, 5 Oct 2012 16:52:50 -0400 Subject: localmodconfig: Document localmodconfig in README Someone (over a year ago :-p) asked me to document localmodconfig in the README file in the source code. I thought it was a good idea but other things were more important and I simply forgot about it. Well, I stumbled on the email asking me about this and I'm sending it out now.
