- """gypsh output module
- gypsh is a GYP shell. It's not really a generator per se. All it does is
- fire up an interactive Python session with a few local variables set to the
- variables passed to the generator. Like gypd, it's intended as a debugging
- aid, to facilitate the exploration of .gyp structures after being processed
- by the input module.
- The expected usage is "gyp -f gypsh -D OS=desired_os".
