# This file builds an Emacs pre-configured with the packages I need
# and my personal Emacs configuration.
#
# On NixOS machines, this Emacs currently does not support
# Imagemagick, see https://github.com/NixOS/nixpkgs/issues/70631.
#
# Forcing Emacs to link against Imagemagick currently causes libvterm
# to segfault, which is a lot less desirable than not having telega
# render images correctly.
