[arch-dev-public] /opt vs. /usr

I remember there was a thread on the ML some time ago about packages still hanging about in /opt and not being moved to /usr. What's the final word on this? I ask because I want to move wicd into extra, and the source package contains binaries and a few scripts, defaulting to /opt. Shall I leave this as is, or move the /opt/wicd to /usr/lib/wicd ? Varun
