Someone on the usenet asked a question on how to clone a directory tree, and the reponses were basically use sed and rsync. I thought, hmm, sounds easy in perl. So I made the simple script below, but some little "perl angel" keeps whispering in my ear, "there should be a way to avoid running mkpath for each dir" . What do you think? Is it too inefficient to run mkpath for each dir, or should there be a way to only create the deepest level in any branch? 
#!/usr/bin/perl -w
use strict;
use File::Find;
use File::Path 'mkpath';

#usage dirtreeclone fromdir todir   No trailing slashes 

my $from = shift || '.';
my $to = shift || "$0-tmp";
my @dirs;

find (sub {push @dirs => $File::Find::name if -d},$from);

foreach my $dir(@dirs){
mkpath("$to/$dir");
}
