Because it's just Ruby:

name "base"
description "Base role applied to all nodes."

all = [

    "recipe[apt]",
    "recipe[build-essential]",
    "recipe[git]",
    "recipe[zsh]",
    "recipe[users::sysadmins]",
    "recipe[sudo]",
]

run_list(all)

env_run_lists(
    "production" => all + ["recipe[chef-client]"],
    "staging" => all,
)

Cheers,

Jay

As mentioned on the wiki page, the env run list is an override, so it totally replaces the default non-env run list if the env matches. Otherwise there would be no way to remove items and ordering would be much harder to grok.
