Emacs major mode for editing f2j source code
Clone the project:
$ git clone https://github.com/zhiyuanshi/f2j-mode.git
Add the directory to your load-path
and require the library.
(add-to-list 'load-path "#{Path to your just-cloned directory}")
(require 'f2j-mode)
And you're good to go! F2J mode will be automatically turned on for .sf
files.
