This script was a candidate for YAPC BC2000 Script of the Year. Found scrawled on a cave wall, it determines the extension of a filename based on the "root" name: 
@pod = qw(HostCycle Instinet index);
$extension{index} = 'pod';
map { 
    $infile_extension = $extension{$_} ? $extension{$_} : '.pm';
    system "pod2html $_.$infile_extension > $_.html";
} @pod;

I was wondering if anyone would care to reduce the number of lines required to do this.
