* Only check the variable if it is set, avoid a log error.
* Pipe errors to SDOUT in case that's why Docker is not showing NPM progress.
* Two messages seemed very similar. Differentiate them.
* Check and install each dependency separately in case a lighter version is already installed.
* Don't require sudo if running as root.
* Use node instead of relying on shebang.
* Allow doing "npm start".
* Remove redirects, did not help see progress.
* Add a note when sudo is used.
* Fix node interpretor location to be arbitrary.
* Woops, need to keep advisories if the value is not set to false.
* Remove warning about apt CLI. Allow npm start to do dependencies.
* `npm start` is not magic, still need to run the install.
* Have `npm start` execute the main run script rather than bypassing dependency checks.
* Use PHP-CLI, smaller install size and more appropriate since only running local scripts.
