# package.el-based emacs packages

## FOR USERS
#
# Recommended: simply use `emacsWithPackages` with the packages you want.
#
# Alterative: use `emacs`, install everything to a system or user profile
# and then add this at the start your `init.el`:
/*
  (require 'package)

  ;; optional. makes unpure packages archives unavailable
  (setq package-archives nil)

  ;; optional. use this if you install emacs packages to the system profile
  (add-to-list 'package-directory-list "/run/current-system/sw/share/emacs/site-lisp/elpa")

  ;; optional. use this if you install emacs packages to user profiles (with nix-env)
  (add-to-list 'package-directory-list "~/.nix-profile/share/emacs/site-lisp/elpa")

  (package-initialize)
*/

## FOR CONTRIBUTORS
#
# When adding a new package here please note that
# * please use `elpaBuild` for pre-built package.el packages and
#   `melpaBuild` or `trivialBuild` if the package must actually
#   be built from the source.
# * lib.licenses are `with`ed on top of the file here
# * both trivialBuild and melpaBuild will automatically derive a
#   `meta` with `platforms` and `homepage` set to something you are
#   unlikely to want to override for most packages
