Create local Emacs package repository from *installed packages* so package upgrade never breaks.

* Why
- Emacs Lisp compile file (*.elc) is not portable for different versions of Emacs. So =emacs.d= copied from higher version of Emacs might crash in lower version of Emacs
- Package installation is fast. 15 seconds to install 115 packages
- The repository could be hosted on USB/Dropbox/GitHub. So you can install packages behind corp firewall
- Tested with Emacs 25, 26, 27 on OSX/Cygwin/Windows10/Linux
* Install
- Download =elpa-mirror.el= to somewhere (say =~/.emacs.d/site-lisp/elpa-mirror/=)
- Add below code into your ~/.emacs,
#+begin_src elisp
(add-to-list 'load-path "~/.emacs.d/site-lisp/elpa-mirror")
(require 'elpa-mirror)
#+end_src

* Usage
=M-x elpamr-create-mirror-for-installed= to create local repository.

To use the repository =~/myelpa/=, insert below code into your =~/.emacs=,
#+begin_src elisp
;; myelpa is the ONLY repository now, dont forget trailing slash in the directory
(setq package-archives '(("myelpa" . "~/myelpa/")))
#+end_src

To update existing local repository, run =M-x elpamr-create-mirror-for-installed= again.

BTW, you can run =elpa-mirror.el= as a independent script,
#+begin_src sh
mkdir -p ~/myelpa && emacs --batch -l ~/.emacs.d/init.el -l ~/any-directory-you-prefer/elpa-mirror.el --eval='(setq elpamr-default-output-directory "~/myelpa")' --eval='(elpamr-create-mirror-for-installed)'
#+end_src
* Tips
** Exclude packages
See =elpamr-exclude-packages=.
** Exclude files/directories in package directory
See =elpamr-tar-command-exclude-patterns=.
** Change output directory,
#+begin_src elisp
(setq elpamr-default-output-directory "~/myelpa")
#+end_src
** Repository on Dropbox
Insert below code into =~/.emacs=:
#+begin_src elisp
;; all-to-list will not override default elpa.
;; So now you have two repositories.
;; One is GNU elpa. Another is myelpa
(add-to-list 'package-archives
             '("myelpa" . "https://dl.dropboxusercontent.com/u/858862/myelpa/"))
#+end_src
** Repository on GitHub
My repository is [[https://github.com/redguardtoo/myelpa]].

Insert below code into =.emacs=:
#+begin_src elisp
(add-to-list 'package-archives
             '("myelpa" . "https://raw.githubusercontent.com/redguardtoo/myelpa/master/"))
#+end_src
