DESCRIPTION
       The environment, environ, is a 0-terminated array of 0-terminated
       strings, called environment variables.  Each environment variable is of
       the form name=value.

       env_get returns the value of the first variable whose name is name, or 0
       if there is no such variable.

       env_pick returns any variable in the environment, or 0 if the environment
       is empty.
