# MacOS X Finder drops silly "._FILENAME" and .DS_Store files for each file it generates 
# a preview for this can ammount to a couple of megs worth of data and on this limited 
# USB drive, that is susbstantial (in the neighborhood of 1-2% of the drive) so this 
# script goes through and takes those files off.  
# 
# You need GNU versions of `find`, `sed`, `du` and `xargs` for this to work.
