Usage: remove_if_proe_created [options] files
 
	This script checks the files to see if they are Pro/ENGINEER files
	and if so moves them to your dumpster directory.
 
	options:	-h =>	this help screen 
			-i =>	inform only (multiple argument).
			-s =>	run silently.

	The -i option can be used to *only* CHECK if an existing file is a 
	Pro/ENGINEER file. The file will not be removed. If this option is used
	the script exits with 0 if one of the files is a Pro/E file.
	If you give the -i option twice (-ii) the script will give a report
	for every file.

	NOTE:	If this scripts complains about not knowing a second extension
		and you want those files to be deleted add the extension in the 
		case list in this script and E-Mail this to me so I can update
		the script for future releases.
