Hi,
 OK, I took a look into the code and I conclude that parm is the tau
 specification.
 Found in interact.c:
     /* quantreg requires a tau specification */
 The tau is the desired quantile (or a list, like you can select when using
 the GUI).
 About API documentation update, I believe that Allin only writes minimal
 documentation in early development of gretl.
 Bye,
 Hélio
