On Guard! Defend yourself! From having to do to much actual text editing, baby!
Where do you get the bop-gun funk from?
cd ~
git clone https://github.com/aredington/bop-gun.git
Next you need to initialize the config. This involves git submodules getting bootstrapped once by you, el-get uses git submodules and manages them for you after it is set up.
cd bop-gun
git submodule init
git submodule update
Create a symlink in your home dir named .emacs.d pointing to bop-gun
ln -s bop-gun .emacs.d
Start up emacs and let it pull down all the dependencies, there's a lot of them. It isn't necessarily likely to boot up cleanly on the first boot, but if you close emacs and reopen it, it probably will.
The el-get recipe for slime depends on cvs. You might need to install that, otherwise you could just roll without slime support.
