leafnode binary package in Ubuntu Precise i386

 Leafnode is a news server suitable for small, limited-bandwidth sites
 with only a few users ('leaf' sites). It keeps track of which groups
 are being read, and downloads only articles in those groups. Leafnode
 has been designed to require no maintenance and to be easy to set up.
 .
 Perl is required to use some optional features of the package for
 handling very low volume newsgroups.
