/**
 * Retrieves, sets and updates aliases for WordPress Installations.
 *
 * Aliases are shorthand references to WordPress installs. For instance,
 * `@dev` could refer to a development install and `@prod` could refer to a production install.
 * This command gives you and option to add, update and delete, the registered aliases you have available.
 *
 * ## EXAMPLES
 *
 *     # List alias information.
 *     $ wp cli alias list
 *     list
 *     ---
 *     @all: Run command against every registered alias.
 *     @local:
 *       user: wpcli
 *       path: /Users/wpcli/sites/testsite
 *
 *     # Get alias information.
 *     $ wp cli alias get @dev
 *     ssh: dev@somedeve.env:12345/home/dev/
 *
 *     # Add alias.
 *     $ wp cli alias add @prod --set-ssh=login@host --set-path=/path/to/wordpress/install/ --set-user=wpcli
 *     Success: Added '@prod' alias.
 *
 *     # Update alias.
 *     $ wp cli alias update @prod --set-user=newuser --set-path=/new/path/to/wordpress/install/
 *     Success: Updated 'prod' alias.
 *
 *     # Delete alias.
 *     $ wp cli alias delete @prod
 *     Success: Deleted '@prod' alias.
