# copies those files with illegal DOS names to libDir/dos-8x3.
# Names are illegal if they are longer than 8x3 chars or if they
# contain uppercase chars. It also tests for name collisions.
# You must first create the directory libDir/dos-8x3 yourself.
# You should remove all files in dos-8x3 if you run it again.
# CHANGE libDir TO THE CORRECT DIRECTORY. RM dos-8x3/* FIRST.
