Infrastructure and commands to manage the environment for processes started within tmux. There is a global environment, copied from the external environment when the server is started and each session has an (initially empty) session environment which overrides it. New commands set-environment and show-environment manipulate or display the environments. A new session option, update-environment, is a space-separated list of variables which are updated from the external environment into the session environment every time a new session is created - the default is DISPLAY.
