# librewolf-hellfire-git
# ----------------------
# VCS package: always tracks the `main` branch of the integration repo
#   https://codeberg.org/FailsafeDX/librewolf-hellfire
# (a fork of LibreWolf's `source` build system with HellFire's mozconfig — full
# LTO, PGO, -march=native, sandbox, JXL, strip — already applied).
#
# Because HellFire's mozconfig uses `-march=native`, this package produces a
# binary tuned to *your* CPU. For a portable prebuilt binary use
# librewolf-hellfire-bin instead.
#
# Unlike a tagged package, the Firefox version is only known after cloning HEAD,
# so the matching Firefox source is downloaded + GPG-verified by the upstream
# Makefile during prepare() rather than declared as a makepkg source.
#
# NOTE: This is a full Firefox/LibreWolf source build with LTO + PGO. Expect a
#       multi-hour compile and ~40 GB of free disk + plenty of RAM.
