how to install just Icon Composer?

hi guys...

i'm having a play with icon development, so wanted Icon Composer... however i couldn't see how to just install that... so now i've ended up with 2.4 gig of stuff i don't want just to get at that tiny little app...

for future reference, how would i just got to this app and leave the rest alone? i'm currently trying to uninstall all the stuff it installed and just keep the icon composer app...

(also on a side note, i had an image and i made pngs in all the different sizes and used icon composer to create an icns file... but the quicklook in candybar is missing the graphics for 256 and 48... does this mean i did something wrong?)
