Author: bdrewery Date: Mon Oct 19 17:04:33 2015 New Revision: 399701 URL: https://svnweb.freebsd.org/changeset/ports/399701 Log: Add some work-in-progress scripts for splitting symbols out into PREFIX/lib/debug. This is only missing the bsd.port.mk pieces to hook it up fully. A blocker for hooking that up has been sub-packages, even though some implementation could be made without them. For now just commit what I have so it is not forgotten.
