Penguin Greetings is a Perl Web-based greeting
card application. It can be run as standard CGI
application or persistently via SpeedyCGI. The
package supports any number of independent ecard
sites running on the same server. Full card
contents are sent as multi-part MIME email. The
HTML for the cards and the creation screens are
rendered from Embperl or Mason templates, making
the program completely customizable by Web
developers and capable of server-side scripting in
Perl. Emailing and database updates are performed
by a separate daemon.
