;;; Commentary:

|
|
;; This package provide the `async-byte-recompile-directory' function
|
|
;; which allows, as the name says to recompile a directory outside of
|
|
;; your running emacs.
|
|
;; The benefit is your files will be compiled in a clean environment without
|
|
;; the old *.el files loaded.
|
|
;; Among other things, this fix a bug in package.el which recompile
|
|
;; the new files in the current environment with the old files loaded, creating
|
|
;; errors in most packages after upgrades.
|
|
;;
|
|
;; NB: This package is advicing the function `package--compile'.
