Usage: Pro_Clean [options] [dir]
 
	Pro_Clean runs Pro_Purge on all (sub-)directories from your HOME
	directory or from [dir]. It also cleans old plot files and other
	Pro/E related temporary files.

	options:	-h   =>	this help screen
			-i   =>	inform only
			-s   =>	run silently
			-ss  =>	run really silently
			-c x =>	with x as a numerical value (1-9) for the
				number of copies to retain (default = 1)
	
	You can make Pro_Clean skip certain directories by adding a file
	with the name .skip_pro_purge to the directory you wish to skip.
	This will only affect the normal purge files. Clean up files like
	*.log, etc. will still be removed.
