title: Ftp transfer the rsync-way
body: <p>I'm downloading a logfile quite often from a ftp-server (which I'm not in control over, btw), and it seems rather rediciolus to download the whole file every time. </p>
  
  <p>So I'm looking for a program (linux-ish) or Perl module that in a way combines ftp and rsync, and only "updates" the file. </p>
  
  <p>The logfile is constantly growing. </p>
  
  <p>Anything like that around?</p>
