+Usage of transmission consumes significant Internet data and system resources.
-#transmission-daemon - lightweight BitTorrent client (daemon)
+Caveat emptor! (That's Latin for "Buyer Beware").
-#transmission-remote-cli - ncurses interface for the Transmission BitTorrent daemon
 
  Access
  ------
 
-You can access transmission using http://box/port or using the command line program.
+You can login transmission using http://box:9091/ or using the command line program.
