I know, right? I'm actually leaning in the direction of making it a little less spartan by having it either accept a parameter for a project name to go directly to that folder, or prompt me to enter a number to select from a list of projects gathered from the folder names in my parent project directory.
Doesn't every developer eventually alias building to 'b' or maybe 'm'? It's like a law of nature. Or you can just rebuild automatically every time you save a file, like js people do.
