Excellent!  Some of this functionality is already mentioned on web
pages such as http://www.lmfdb.org/EllipticCurve/3.3.148.1/356.1/a/1
(after clicking the "Show commands for ... Pari/gp" near the top.  If
those commands are not correct, please let me know (they were written
by Aurel).  I notice that he did not include the field as a parameter
in the ellinit().

Are there plans to include Denis Simon's gp scripts for 2-descent,
over Q and over number fields, as standard?
