Unfortunately, the Cisco AnyConnect client for Mac conflicts with Pow. And by "conflicts", I mean it causes a grey-screen-of-death kernel panic anytime you connect to the VPN and Pow is installed.

As an alternative, there is OpenConnect, a command-line client for Cisco's AnyConnect SSL VPN.

Here's how to get it set up on Mac OS X:

OpenConnect can be installed via homebrew:
```
 brew update
```

brew install openconnect

	! The following 2 lines are what I use to display news.ycombinator.com

	! Limit comments to 70 characters wide, making them easier to read
	news.ycombinator.com##.comment:style(max-width: 70ch !important; overflow: hidden !important;)

	! Invert the colours of the site, making a dark mode that I like
	! `invert(95%)` does most of the work,
	! but you can tweak the hue-rotate value to fine tune the colours
	news.ycombinator.com##html:style(filter:invert(95%) hue-rotate(200deg); background: white)

	#!/usr/bin/env bash

	set -Eeuo pipefail
	trap cleanup SIGINT SIGTERM ERR EXIT

	usage() {
	cat <<EOF
	Usage: $(basename "${BASH_SOURCE[0]}") [-h] [-v] [-f] -p param_value arg1 [arg2...]
