Keep favorite info pages in $HOME

Info is a handy document system most emacs fans love. We can learn Info, Emacs Basics, Emacs Lisp, Magit and blah blah blah through the system and look up any detail every time we need without leaving Emacs, so that I install many info pages into /usr/local/info, /usr/share/info and /usr/share/local/info. However, when I need to migrate all data to new computer, keeping my info pages is really a nightmare. So I add a few of lines shown below into ~/.emacs

(custom-set-variables
  '(Info-default-directory-list 
     (append Info-default-directory-list 
             '("~/.info"))))

and put all info pages I collected before into ~/.info

Now I just need to migrate all files in my $HOME to new computer.
