Module to add [node inspect](https://nodejs.org/api/debugger.html)'s [V8-inspector-protocol](https://chromedevtools.github.io/devtools-protocol/v8/Debugger)
debugger support to emacs
[realgud](https://elpa.gnu.org/packages/realgud.html).

Note: for node before version 6.3, an older protocol is used.  In realgud,
that debugger for the older version is called [`node-debug`](https://elpa.gnu.org/packages/realgud-node-debug.html).

It is similar to [ELPA trepan-ni](https://elpa.gnu.org/packages/realgud-trepan-ni.html), but the realgud interaction here is inferior.
