+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' ],

+                    The below code tries to infer the last known ABI compatible version
+                    that we have recorded in the abi_crosswalk.json when an exact match
+                    is not possible. The reasons for this to exist are complicated:
+
+                       - We support passing --target to be able to allow developers to package binaries for versions of node
+                         that are not the same one as they are running. This might also be used in combination with the
+                         --target_arch or --target_platform flags to also package binaries for alternative platforms
+                       - When --target is passed we can't therefore determine the ABI (process.versions.modules) from the node
+                         version that is running in memory
+                       - So, therefore node-pre-gyp keeps an "ABI crosswalk" (lib/util/abi_crosswalk.json) to be able to look
+                         this info up for all versions
+                       - But we cannot easily predict what the future ABI will be for released versions
+                       - And node-pre-gyp needs to be a `bundledDependency` in apps that depend on it in order to work correctly
+                         by being fully available at install time.
+                       - So, the speed of node releases and the bundled nature of node-pre-gyp mean that a new node-pre-gyp release
+                         need to happen for every node.js/io.js/node-webkit/nw.js/atom-shell/etc release that might come online if
+                         you want the `--target` flag to keep working for the latest version
+                       - Which is impractical ^^
+                       - Hence the below code guesses about future ABI to make the need to update node-pre-gyp less demanding.
+
+                    In practice then you can have a dependency of your app like `node-sqlite3` that bundles a `node-pre-gyp` that
+                    only knows about node v0.10.33 in the `abi_crosswalk.json` but target node v0.10.34 (which is assumed to be
+                    ABI compatible with v0.10.33).
