+ Non volatile environment variables begin with "nv.". They behave like
+ global variables above, but their values are saved in the environment
+ storage with 'saveenv' and thus are persistent over restarts. nv variables
+ are coupled with global variables of the same name. Setting "nv.foo" results
+ in "global.foo" changed also (but not the other way round: setting "global.foo"
+ leaves "nv.foo" untouched). The idea is that nv variables can store defaults
+ while global variables can be changed during runtime without changing the
+ default.
