That's what I do. For each Perl module RPM I check for the version of
the Perl module, not the version of any RPM that happened to contain
it. That's what the "CheckModuleVersion" program does in the
distributions.

Agreed.

I do force some of them, agreed.

How many ISP's (most of my useres) can't afford the bandwidth to
download a few megs of a package? You only need to do it at the very
most once every few months. Most people waste more than that in a
day's random web surfing.

Adding more options to the list of downloads encourages new users to
download the wrong one. Most people don't know if they want the full
package or just the single RPM, so I would much rather keep things
simpler for the masses. The enlightened among you can pull out the 1
file you want pretty easily. And what when the requirements change?
They have done so in the past, and then you will need other files from
the distribution as well.

I want to keep it as simple as possible. Installing MailScanner is
already quite hard enough! If you have suggestions for how I could
make it simpler for the masses, please tell me. I'm hoping that
someone will start working with Dag soon to get MailScanner into his
archive in a form where one yum command will install/upgrade
MailScanner and all its requirements at one go.
