# Title: Build Dpkg for LibreWolf
# Purpose: Prepare initial assets for running "dpkg-buildpackage -b -us -uc" for LibreWolf by adapting distro Firefox assets
# History:
#    2021-03-10 add initial Ubuntu support
#    2022-01-18 modified to use "source" repo instead of "common" for version 97.0.1
#    2023-05-07 dropped repo "linux" which is disused
# Usage:
#    Can send these final assets up to Open Build Service
# References:
#    Script numbers from https://gitlab.com/librewolf-community/browser/linux/-/tree/master/binary_tarball/scripts
# Improve:
#    Make this idempotent. Right now it is very much not.
# Dependencies:
#    wget, git, tar, awk, sed, jq

# Aborts the script upon any failure
