Yes, it ignored the following package directories from removed recipes: 
module-init-tools-3.16-r0 & module-init-tools-cross-3.16-r0.   My 
preference would be to have the tool delete them.

I also noticed that the regex filters missed "iputils-s20101006-r3", so 
a tweak to pick this up is probably warranted (or at least flag it at 
the bottom of the regex loop as not being matched by any of the filters).

Related question: why not add an option to the tool to have it go ahead 
and also delete the artifacts from the obsolete packages left in stamps 
and buildstats?
