Usage: ProENGINEER [options] [command] [startup-options]
 
	ProENGINEER is the startup command for Pro/ENGINEER.
 
	options: -h 		=> this help screen 
		 -n 		=> do not show confirmation window if Pro/E
		 		   crashes or if license is already running.
		 -r 		=> Run license remote. Do not reset REMOTE
		 		   variables.
		 -c 		=> Force Pro/E to crash when a trail file runs
		 		   out of sequence.
		 -v		=> Check which version of Pro/E is installed.
		 -k		=> Keep $HOME/.pdm-links file (default is to
		 		   remove)
		 -p proxx	=> Use proxx as start command.

	If you specify the -s option Pro/ENGINEER will startup from current
	directory.
	If you specify [command] this script will use the command to startup
	Pro/ENGINEER if it exists in the command-list.

	Examples (combinations are possible):
		ProENGINEER test_model.asm 			(retrieve model)
		ProENGINEER 1111				(debugging mode)
		ProENGINEER trailfile.txt			(start trail
								file)
		ProENGINEER -1 0 3 -batchfile batchfile.txt	(Run plot
								batch-file)
		ProENGINEER -scn trail.txt			
		etc...

	It returns the following exit codes:
		0 - OK
		1 - Pro/ENGINEER has crashed (trail file did not end with #EXIT)
		2 - unknown option or user break.
