[thelist] Rollover code from evolt

[Tony Grimes]

Anthony,
     Which code do you use most of the time? I can hack Perl, so
JavaScript shouldn't be hard to learn; I've just never bothered before
(I'm usually a project manager). This code will only be for the odd site
that I do start-to-finish, so complexity doesn't really matter; as long as
it's solid.
