A simple installer for site-elisp.

Assume that you have site-lisp/ and a working copy of this repository named repos/tarao/ in the same directory. Then, following commands automatically pull repositories under repos/ and install *.el from those repositories:

cd repos
ln -s tarao/install.rb
./install.rb

Set default-file-coding-system according to the regular expressions of file names.

(require 'default-file-coding-systems)
(setq default-file-coding-system-alist
      (append
       '(("\\.tex$" . euc-jp-unix)
         ("\\.sty$" . euc-jp-unix)
         ("\\.bib$" . euc-jp-unix))
       default-file-coding-system-alist))
