Create inline GIF favicons
/* Bill Ticehurst, 2020
Emits a minimal 16 x 16 gif suitable for use as an inline favicon
GIF spec at https://www.w3.org/Graphics/GIF/spec-gif89a.txt for the structure
Favicon formats supported at https://en.wikipedia.org/wiki/Favicon
For a transparent GIF (color_table = false, depend_on_background = true) this emits:
<link rel="icon" href="data:image/gif;base64,R0lGODlhEAAQAAAAACwAAAAAAQABAAACASgAOw==">

ARM64 Linux on Win10

Below are the steps to get an ARM64 version of Ubuntu running in the QEMU emulator on Windows 10.

Install QEMU

Install for Windows from https://qemu.weilnetz.de/w64/ (I used qemu-w64-setup-20181211.exe)

Put C:\Program Files\qemu on your PATH, and run the below to check it's working (which will list out the CPUs the AArch64 emulator can emulate):

qemu-system-aarch64 -M virt -cpu help

before processing with the below (that specific filename is expected).
