The loginfo file is how one sets up commit emails – automated emails that go out to everyone working on a project whenever a commit takes place. (It may seem counterintuitive that this is done in loginfo instead of commitinfo, but the point is that one wants to include the log message in the email). The program to do the mailing – contrib/log.pl in the CVS source distribution – can be installed anywhere on your system. I customarily put it in the repository's CVSROOT/ subdirectory, but that's just a matter of taste.
You may need to edit log.pl a bit to get it to work on your system, possibly changing the first line to point to your Perl interpreter, and maybe changing this line
$mailcmd = "| Mail -s 'CVS update: $modulepath'";
to invoke your preferred mailer, which may or may not be named
listerizer CVSROOT/log.pl %s -f CVSROOT/commitlog -m email@example.com RoadMail CVSROOT/log.pl %s -f CVSROOT/commitlog -m firstname.lastname@example.org bk/*score CVSROOT/log.pl %s -f CVSROOT/commitlog -m \ email@example.com
%s expands to the names of the files being committed; the -f
option to log.pl takes a file name, to which the log message will
be appended (so CVSROOT/commitlog is an ever-growing file of log
messages); and the -m flag takes an email address, to which
log.pl will send a message about the commit. The address is
usually a mailing list, but you can specify the -m option as many times
as necessary in one log.pl command line.
