You're right, the documentation doesn't say that the tool is added to the path.
Rather, the documentation invokes `ncrunch.exe` as if it's local to the command line prompt -or- it's on the path.
But nothing in the documentation indicates where the tool is.
Reading the docs, I assumed "it must be on the path env", because it's simply invoked without a path.
Once I realized it wasn't on the path, I had no idea where to find it in order to invoke it.
Does that make sense?
