opencu is a replacement for uudp-cu in the sense that they provide a binary
with the same name and users installing opencu are unlikely to also uudp-cu.
The binaries are however not 100% cli compatible, so scripts written for
uudp-cu won't always work with opencu without adjustments.
It looks like we have a similar situation with netcat and netcat-openbsd where
the latter declares Breaks+Replaces netcat, so this seems like the correct
solution.
