Author: uqs Date: Fri May 11 16:08:51 2012 New Revision: 235275 URL: http://svn.freebsd.org/changeset/base/235275 Log: Update guidelines on user/ and projects/ The goal is to make it clearer where future branches should be created. A consistent layout under projects/ would also help with conversions to other VCSes that do not follow the everything-is-a-subdir dogma. TL;DR - If it's a branch of head that you want to merge back -> projects/ - If it's something else -> user/your-login/ (e.g. portmaster, stress2, etc.) Discussed on: developers Silence by: peter Modified: user/GUIDELINES.txt Changes in other areas also in this revision: Modified: projects/GUIDELINES.txt Modified: user/GUIDELINES.txt ============================================================================== --- user/GUIDELINES.txt Fri May 11 16:04:55 2012 (r235274) +++ user/GUIDELINES.txt Fri May 11 16:08:51 2012 (r235275) @@ -1,16 +1,9 @@ $FreeBSD$ -Golden rules: -Rule #1: TAKE IT EASY!
