[erlang-questions] How to file bug for obsolete reference in email package?

[Peter K Chan]

I installed the email package using CEAN, and I noticed that the actual
send command uses unix:cmd, which no longer exists in recent
distribution of Erlang. I changed it to os:cmd and it ran fine.

It doesn't look like the email package, authored by Joe Armstrong, has
been updated in the past 10 years.

It's a simple 3-character change. Who and where should I file the bug
for this? Do I file it at CEAN or do I email Joe?
