+// for you. None of the data personally identifies you, your employer or your
+// app, but it *will* help us understand what language you use, what Node.js
+// versions you target, etc. Having this info will help prioritizing our time,
+// adding new features and deprecating old features. Collecting an anonymized
+// application path & anonymized machine identifier is the only way for us to
+// count actual usage of the other metrics accurately. If we don’t have a way to
+// deduplicate the info reported, it will be useless, as a single developer
+// `npm install`-ing the same app 10 times would report 10 times more than another 
+// developer that only installs once, making the data all but useless.
+// No one likes sharing data unless it’s necessary, we get it, and we’ve
+// debated adding this for a long long time. If you truly, absolutely
+// feel compelled to not send this data back to Realm, then you can set an env
+// variable named REALM_DISABLE_ANALYTICS.
+//
+// Currently the following information is reported:
+// - What version of Realm is being installed.
+// - The OS platform and version which is being used.
+// - Node.js, v8, libuv, OpenSSL version numbers.
