In idiomatic English, it means to start with the simple, not with the complex.


This sounds like one of those places where cobbling something together out 
of command line programs is an exercise in frustration and the time might be 
better spent on working with the source code and libraries to get something 
that does exactly what you want. Or at least reading the source code to see 
what messages come from where.
