I'm sure it'd look much nicer in lisp, or cleaner in perl if writen by
a perl expert ;)


#!/usr/local/bin/perl -w
use strict;

my $a = shift;
print f(0) . "\n";

sub f {
    my $b = shift;
    my $bq = ($b>0?'`':'');
    my $bs = '\\'x($b>1?((1<<$b-1)-1):0);

    return $bs . $bq . "echo $b " . (($b<$a)?f($b+1):'') . $bs . $bq;
}
