+# This file builds an Emacs pre-configured with the packages I need

+# On NixOS machines, this Emacs currently does not support

+#
+# Forcing Emacs to link against Imagemagick currently causes libvterm
+# to segfault, which is a lot less desirable than not having telega
+# render images correctly.
