# Brendan's zshrc.
# This file should contain zsh specific configuration, and should also source any generic
# configuration files such as ~/.aliases. Lastly it will connect to an existing tmux session,
# or start the server if there is none.
#
# One of my primary aims is to keep this file as fast as possible, to reduce startup time when
# creating tmux panes. This is the reason I don't use oh-my-zsh, for example. I've actually
# found switching away from oh-my-zsh to be pretty simple.
