Hello all,
did anyone try this? It does not work for me, I tried running it on a

(http://www.kcmetro.cc.mo.us/longview/ctac/powerpoint/ct.ppt) as well as

empty text files and error messages like this (copy of stdout, with
empty lines removed -- there were three before each line starting with a
slash):
