Ansible Role Oh My ZSH

This is a basic Ansible role to enable and configure Oh My Zsh on Fedora, Ubuntu, or MacOS. It should also work on many other *nix variants. It performs the following tasks:

• Install and minimally configure Zsh:
  • make sure it exists,
  • set it as the default shell for the user specified by the role.
• Install Oh My Zsh for each specified user (in ~/.oh-my-zsh by default).
• Configure (Oh My) Zsh by optionally creating a .zshrc file for each specified user.
• Alternately, configure Zsh by adding a block of lines to individual users' .zshrc files.
