[gentoo-user] script to calculate download size

[Selentek 24331-03]

There is script to calculate size of files needs to emerge packet.

emerge -p need root privileges and get_size need it too

Example:
  $ sudo get_size cannonsmash
media-libs/sdl-mixer-1.2.5-r1
                         914Kb   SDL_mixer-1.2.5.tar.gz (ok)
    Pkg size: 914Kb   Download: 0
games-simulation/cannonsmash-0.6.5
                         1435Kb          csmash-0.6.5.tar.gz
                         1045Kb          danslatristesse2-48.ogg
    Pkg size: 2481Kb   Download: 2481Kb
Total Size: 3395Kb      Download: 2481Kb
