Create and capture DNS and mDNS query and response packets to disk as binary and/or JSON.
Options are similar to the Unix `dig` command.
Install
Install with git
-------
```bash
# Install the latest of v1.x
npm install -g 'git+https://git@git.daplie.com/Daplie/dig.js.git#v1'
```
If you don't have `git` installed you can also try the npm repo:
```bash
# Install exactly v1.0.0
npm install -g 'git+https://git@git.daplie.com/Daplie/dig.js.git#v1.0.0'
```
Install without git
-------
Don't have git? Well, you can also bow down to the gods of the centralized, monopolized, concentrated, *dictator*net
(as we like to call it here at Daplie Labs), if that's how you roll:
```bash
npm install -g dig.js
