+// This file is a bit weird, so let me explain with some context: we're working
+// to implement a tool called "Corepack" in Node. This tool will allow us to
+// provide a Yarn shim to everyone using Node, meaning that they won't need to
+// run `npm install -g yarn`.
+//
+// Still, we don't want to break the experience of people that already use `npm
+// install -g yarn`! And one annoying thing with npm is that they install their
+// binaries directly inside the Node bin/ folder. And Because of this, they
+// refuse to overwrite binaries when they detect they don't belong to npm. Which
+// means that, since the "yarn" Corepack symlink belongs to Corepack and not npm,
+// running `npm install -g yarn` would crash by refusing to override the binary :/
+//
+// And thus we have this preinstall script, which checks whether Yarn is being
+// installed as a global binary, and remove the existing symlink if it detects
+// it belongs to Corepack. Since preinstall scripts run, in npm, before the global
+// symlink is created, we bypass this way the ownership check.
+//
+// More info:
+// https://github.com/arcanis/pmm/issues/6
