Print"  No warrantee as to suitability or operation is given or implied,"
Print"  so use at your own risk.  Note that some programs may use a zero-"
Print"  length file as a flag of some sort, or there may be an empty"
Print"  directory that is needed at certain other times for the proper"
Print"  operation of some program.  That is the type of issue that would"
Print"  become a problem if the needed file or directory is deleted."
Print"  While this approach is rarely today, some programs have behaved"
Print"  in this fashion in the past, and others may again in the future."
