From 85dfd522f885ee4ec0b0b4efa1fdd9c650e243be Mon Sep 17 00:00:00 2001 From: Jake Edge Date: Mon, 19 May 2014 17:48:24 -0600 Subject: [PATCH] staging/skein: rename files and clean up directory structure Clean up file names and locations. Get rid of include/ directory and move those up to the top-level. Rename files to get rid of upper case. Remove skeinBlockNo3F.c as it was unused (temporary file or something?).
