Alf - Out of this World Zsh
Alf is an out of this world super fast and configurable framework for zsh; it's modeled after Prezto and Antigen. The framework is currently utilizing Oh My Zsh (framework, plugins and themes) and optionally Prezto's plugins under the covers; and offers standard defaults, aliases, functions, auto completion, automated updates and installable prompt themes and plugins.
Why another framework?
At my work I needed to support a similar shell environment across OS X, Windows, and Parallels (running a virtual machine with an OS X host). Originally I was able to get Cygwin running with Oh My Zsh, but I wasn't really happy with the performance. So I started scripting and hacking around and learning Bash and Zsh.
