From d8f9d05baee3abd4feb0a5b2f2afe467e919c6b9 Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Fri, 8 Aug 2014 15:53:52 -0500 Subject: wic: Rename /mic to /wic As well as any other stray instances of mic in the codebase that can be removed. We don't really need to carry around legacy naming, and the history is in git.
