done.
installation was easy.
usage in root was mostly easy; between 40 and 50 MB recovered.
Control over localizations was tedious. Suggest either (better) a way
to disable localization checks, or (not as good) a single check box
equivalent to checking all the localizations to be retained. I'll try
to figure out localizations some other time.
I have not yet tried this tool as a non-privileged Fedora user. I have
not yet installed it on my windows-7 box.
Next step outside of bleachbit is automating clean-up of stuff left
behind by akmods when patching. I'm researching this.
thanks,
Bill.
