/**
|
|
* Lerna installs all the example dependencies into the root `node_modules`.
|
|
* To run the examples they need to have access to executables from npm dependencies in their $PATH.
|
|
* If you run `npm start` in a dependency folder, the root `node_modules/.bin` is not in the $PATH.
|
|
*
|
|
* This proxy executable can be run from the repository root using `npm run example`, so the root
|
|
* `node_modules/.bin` will be in the $PATH. It then runs `npm start` in the specific example folder,
|
|
* which will inherit the $PATH, so the example has access to executables from npm dependencies in both
|
|
* its own and in the root `node_modules`.
