To set up my dotfiles, although I'm not in enough of a routine for it to be truly useful.

    tmux:
    	ln -s $(CURDIR)/.tmux.conf $(HOME)/.tmux.conf
    	tmux source-file ~/.tmux.conf
    
    reload-tmux:
    	tmux source-file ~/.tmux.conf
    
    gitconfig:
    	ln -s $(CURDIR)/.gitconfig $(HOME)/.gitconfig

cd ~/configs then make whatever. ~/configs itself is a git repository.
