To read a file completely, you should use
    undef $/;
That works even if the file has the character you think is unused!

PLEASE, use octal when you're looking for a bit pattern -- it's more
portable, and clearer:

$LF = "\012";
$CR = "\015";
$DOSeol = "$CR$LF";
$MacEol = "$CR";
$UNIXeol = "$LF";

if ($text =~ /$DOSeol/o) {
    $text =~ s/$DOSeol/$MacEol/og || die("Ahhh! Couldn't convert to MAC.\n");
} elsif( $text =~ /$UNIXeol/o ) {
    $text =~ s/$UNIXeol/$MacEol/og
        || die("Ahhh! Couldn't convert from Unix.\n");
} else {
    $text =~ s/$MacEol/$DOSeol/og || die("Ahhh! Couldn't convert to DOS.\n");
}

Remember, "\n" does NOT mean ASCII CR!!!!!
