BleachBit deletes unnecessary files to free valuable disk space, maintain privacy, and remove junk. Rid your system of old clutter including cache, cookies, Internet history, localizations, logs, temporary files, and broken shortcuts. Designed for Linux and Windows systems, it wipes clean Adobe Reader, APT, Bash, Beagle, Chromium, Epiphany, Firefox, Flash, GIMP, Google Chrome, Google Earth, Internet Explorer, Java, KDE, OpenOffice.org, Opera, RealPlayer, Safari, Skype, VIM, XChat, Yum, and more.

To try it out in Foresight Linux, open Terminal and write:

sudo conary update bleachbit=@fl:2-devel

(thanks Mark_T for recipe help, i needed a application like this one)
