Source repository?

[Boylan, Ross]

After checking various places I found https://alioth.debian.org/forum/forum.php?forum_id=2929 and tried the recommended command:
ross at ross-mail:/usr/local/src$ date; git clone https://alioth.debian.org/anonscm/git/pkg-cyrus-imapd/pkg-cyrus-imapd-2.4.git
Fri May  5 14:50:05 PDT 2017
Cloning into 'pkg-cyrus-imapd-2.4'...
fatal: repository 'https://alioth.debian.org/anonscm/git/pkg-cyrus-imapd/pkg-cyrus-imapd-2.4.git/' not found

Guessing, I tried
ross at ross-mail:/usr/local/src$ date; git clone https://alioth.debian.org/anonscm/git/pkg-cyrus-imapd/pkg-cyrus-imapd.git
Fri May  5 14:51:12 PDT 2017
Cloning into 'pkg-cyrus-imapd'... 
warning: You appear to have cloned an empty repository.
Checking connectivity... done.
also without luck.

I know apt-get source will fetch it, but I was hoping to get something more integrated with the revision history.
https://sources.debian.net/src/cyrus-imapd-2.4/stable/ is good for browsing on the web, but doesn't seem designed for other uses.

I guess I'll use apt-get, but am curious about other methods.

Thanks.
