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.
