Sinburn (sinburn-theme.el) is my own version of the Zenburn theme for emacs.
There are quite a few different zenburn-for-emacs versions floating around the internet – some of my own, see zenburn-for-emacs with the color-theme package, and zenburn-for-emacs-24.
To (hopefully) reduce confusion, I’ve renamed my version Sinburn, and this is where I will do my further customizations.
Note, sinburn-theme.el is for Emacs 24 – which is not released officially
yet, but widely used.
Drop sinburn-theme.el somewhere in your custom theme directory (see the
variable custom-theme-directory), and execute M-x load-theme RET sinburn
RET.
