See chapter 11, section 2 of the User's Guide, sub-head "Built-in 
strings".  You have "@userdir" which gives the user directory, 
which must be writable (or else gretl will fail at startup).

We could maybe add a "getenv" function for strings, so you could 
grab variables in the external environment.
