BMK without params - showing help but also "command line error"

[GWRon]

When trying to find out about potential parameters of bmk you simply excute it. but it also outputs an "error" (via stderr):

$ ./bmk
Command line error : Not enough parameters

Usage: bmk <operation> [options] source

Operations :
	makeapp
		Builds an application from a single root source file.

	makelib

The message should only be spit out if there was a parameter lacking further ones - or an unsupported first parameter
