"""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".
