     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.
