Prezto é um garfo de Oh-My-Zsh destinado a ser saner / cleaner 1 e use a sintaxe zsh 2 .
Como tem havido uma questão de quebra de links, aqui estão as citações:
1: Por John Stevenson
Prezto has been rewritten by the author who wanted to achieve a good zsh setup by ensuring all the scripts are making use of zsh syntax. It has a few more steps to install but should only take a few minutes extra.

In case it isn't clear, prezto is a fork of oh-my-zsh which has basically been rewritten bit by bit to make everything much cleaner and saner. I highly recommend it. The history-substring-search and syntax-highlighting modules are brilliant. You will be the envy of all your friends and neighbours.
