Score is -141
Accept this solution? [Y/n/q/?] 
---------------------------------------

I'm wondering

- why file-rc will be automatically removed? I saw many packages are
depending on it.

- why are these packages installed? who need them? 

  bittorrent gs-esp libcupsimage2 mplayer-k6 podracer

- why there are 32 packages to be removed? what triggers the removal?

- what are all the mencoder-k6 mplayer-k6 stuff? I don't have anything
installed. why aptitude mention about them? Here are my installed packages:

$ dpkg -l | grep mencoder

$ dpkg -l | grep mplayer
ii  mplayer        1.0-pre8-0.1   The Ultimate Movie Player For Linux
ii  mplayer-doc    1.0-pre8-0.1   Documentation for mplayer
ii  mplayer-skin-b 1.5-0.5        default skin for mplayer

- what does the "Score" indicate? Any meaning related with the score range?

thanks
