/*
 | 
						|
 | 
						|
Here we gather node-pre-gyp generated options (from versioning) and pass them along to node-gyp.
 | 
						|
 | 
						|
We massage the args and options slightly to account for differences in what commands mean between
 | 
						|
node-pre-gyp and node-gyp (e.g. see the difference between "build" and "rebuild" below)
 | 
						|
 | 
						|
Keep in mind: the values inside `argv` and `gyp.opts` below are different depending on whether
 | 
						|
node-pre-gyp is called directory, or if it is called in a `run-script` phase of npm.
 | 
						|
 | 
						|
We also try to preserve any command line options that might have been passed to npm or node-pre-gyp.
 | 
						|
But this is fairly difficult without passing way to much through. For example `gyp.opts` contains all
 | 
						|
the process.env and npm pushes a lot of variables into process.env which node-pre-gyp inherits. So we have
 | 
						|
to be very selective about what we pass through.
 | 
						|
 | 
						|
For example:
 | 
						|
 | 
						|
`npm install --build-from-source` will give:
 | 
						|
 | 
						|
argv == [ 'rebuild' ]
 | 
						|
gyp.opts.argv == { remain: [ 'install' ],
 | 
						|
  cooked: [ 'install', '--fallback-to-build' ],
 | 
						|
  original: [ 'install', '--fallback-to-build' ] }
 | 
						|
 | 
						|
`./bin/node-pre-gyp build` will give:
 | 
						|
 | 
						|
argv == []
 | 
						|
gyp.opts.argv == { remain: [ 'build' ],
 | 
						|
  cooked: [ 'build' ],
 | 
						|
  original: [ '-C', 'test/app1', 'build' ] }
 |
