~/.zshrc and ~/.zprofile setup. Nothing too special.

* ~/.zprofile

Make sure that zsh sources ~/.profile correctly on login.

#+BEGIN_SRC sh :tangle tmp/.zprofile :results replace
emulate sh
source ~/.profile
emulate zsh

# zsh does this differently
login_shell()
{
  [[ -o login ]]
}
#+END_SRC

* ~/.zshrc

Zsh configuration, its not too crazy... I think. Don't judge me.
