Can anyone help

[aburke]

if ($ENV {'REQUEST_METHOD'} eq 'POST') {
read(STDIN, $buffer, $ENV {'CONTENT_LENGTH'});
@pairs = split (/&/, $buffer);
foreach$pair(@pairs) {
($name, $value) = split (/=/, $pair);
$value =~ tr/t/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack ("C", hex ($1))/eg;
$FORM{$name} = $vaule;
}
}

I have just started in CGI/Perl programming and would like to know what this code does. I sort of know what I think it is trying to do, but I'm not sure. If someone could explain it to me that would be so great.

Thanks for the help in advance.

It converts the query string:

?action=newreply&threadid=27509

or similar...

into an associative array:
$FORM{'action'} = "newreply"
$FORM{'threadid'} = "27509"
