# This script will compile and install a static FFmpeg build with

#   with CUDA capability 8.6 (RTX 3080) (see ccap below).
# It assumes NVIDA drivers are installed and that you have a

# Script to automate VPN client start and entering credentials
#   "xdotool key" and "xdotool type" commands were not working
#   most of times when using the --window option, so the script
#   uses the "wmctrl" to switch window focus before typing or
#   pressing keys.
# === BEFORE FIRST EXECUTION ===
#   Set VPN_USERNAME below;
#   Store the VPN password once with secret-tool:
#       secret-tool store --label "Cisco VPN credentials" vpn_client "$VPN_USERNAME"

How to use this CSS:

0. Install the Sidebery extension: https://addons.mozilla.org/en-US/firefox/addon/sidebery/.
1. In Sidebery settings:
    a. Set the title preface must as "[S] " (without quotes).
        This is used by CSS rules below to identify when Sidebery is active.
    b. Set 'Tabs tree structure' to false -- this stylesheet doesn't adapt to
        multiple tab levels, but feel free to tweak it!
    c. Copy and paste the "SIDEBERY STYLES" section below in
