Code sample: perl

I haven't been using perl all that long, but even so it was a head-scratcher deciding which program I should put up here as an example. But I got a hint from Larry Wall, the designer of perl. In his 1998 State of the Onion address he demonstrated his own first CGI script, (newly written!) with the observation that showing off one's first CGI script is to be expected.

Just what I needed to know.

The program that follows was indeed my first CGI script, although it underwent major surgery since it first saw daylight and hardly resembles its original self. Still, it was my first. Originally, it just generated a header and footer with no content; now it shows a fortune cookie from an external program each time it is called. I publish it now with Larry's implicit blessing. ;-)
