Initial setup

Install xmlstarlet
- sudo apt install xmlstarlet, sudo pacman -S xmlstarlet, etc. depending on your distribution.
Install apktool, make sure its available in PATH
- https://ibotpeaches.github.io/Apktool/install/
- Run apktool if framework-res.apk, apktool if SystemUIGoogle.apk to install framework for apktool.
  This is necessary for proper extracting.
  (generally found in /system/framework/, /system_ext/priv-app/)

Extracting / updating extracted overlays

Basically the same as regular extract-files

./extract-files.sh /path/to/a/dump

Removing certain overlays

If certain overlays are not required, you can simply add them to exclude-tag.txt, those will be removed from the extracted overlays.

Miscellaneous information

The main changes here are the addition of apktool and xmlstarlet, to allow us to extract the necessary overlays from some RROs.
Since the process does take a while, to speed it up, all extraction is done in the background.
This might not be suitable for weaker systems if there is a very high number of overlays to be extracted.
