Where can I download the source for cron utility?

I have 开发者_开发问答searched for the source for cron, to adapt it to modify/exend it. I cant locate it (thought it would be in coreutils).

Anyone knows where I can get the sources for cron?

BTW, I am running on Linux (Ubuntu 10.0.4)

---

apt-get source cron

apt-get source cron should fetch you the sources assuming you have the repositories properly setup.

---

Just for the record, I tried to run just that (apt-get source cron), and the tool complains that the archives are not found (404 Not Found). A quick

sudo apt-get update

will fix the situation and then we could do a

apt-get source cron

GNU sponsorships mcron (Mellor's cron). Homepage at http://www.gnu.org/software/mcron/. Sources at http://git.savannah.gnu.org/cgit/mcron.git

I don't know if Ubuntu uses this, though.
