Informing others about commits

[Tomáš Velek]

Hello,
don't you know where is described (with details if it's possible) creating of scripts?
I need email to be send to concrete people, after the concrete event (mostly commit or add and delete). To which people, it dependes on which modul was commited.
It is better to use 'loginfo' or 'notify' file? I have tried both ways, but it  mostly report me this error:
cannot write entry to notify filter: Mail -s address@hidden "Notification": Bad file descriptor

And where I can edit SMTP address in CVS?

Thanks all for every help.

Tomas
