oh-my-zsh theme for presentations (hides prompt features based on path)
# problem: when presenting, I want to obscure
# my prompt to act like it's at root of file system
# and be very basic with no git info, etc.
# solution: this theme lets you set a ENV to the path
# of your presentation, which will help remove unneeded prompt
# features while in that path
# oh-my-zsh theme for presenting demos
# based off the default rubbyrussell theme
