 # BUGS
 
-# * Sort order is a bit strange.
-# * ImageMagick's Montage doesn't handle long filenames nicely.
 # * Some transparent images (many .eps files) presume a white background
 #   and will not show up if your terminal's background is black.
 # * This file is getting awfully long for a one line kludge. :-)
