is there a tarsnap pkg avaialble for debian

[Harry Putnam <reader@newsguy.com>]

I don't know much about what all sources are available for debian and
currently just using the /etc/apt/sources.list established by the
default install:
   deb http://ftp.us.debian.org/debian/ squeeze main
   deb-src http://ftp.us.debian.org/debian/ squeeze main
   
   deb http://security.debian.org/ squeeze/updates main
   deb-src http://security.debian.org/ squeeze/updates main
   
   # squeeze-updates, previously known as 'volatile'
   deb http://ftp.us.debian.org/debian/ squeeze-updates main
   deb-src http://ftp.us.debian.org/debian/ squeeze-updates main

Is there a source for a `tarsnap' pkg
 
  (http://www.tarsnap.com/index.html) 

that is accessible with `aptitude'?
