#4822: Tweak to the error message for EllipticCurve
---------------------------+------------------------------------------------
 Reporter:  ljpk           |       Owner:  was       
     Type:  defect         |      Status:  new       
 Priority:  minor          |   Milestone:  sage-3.2.2
Component:  number theory  |    Keywords:            
---------------------------+------------------------------------------------
 I was using SAGE with the small version of the CremonaDatabase, and tried
 the following, which does not work because the conductor is too high:
 {{{
 EllipticCurve("10001a1")
 }}}

 I think it would be useful if the error message not only said "this curve
 is not in the database" (which is indeed true) but also checked to see if
 one was using the small database of curves, and if so told the user how to
 access the larger version
 using the incantation
 {{{
 !sage -i database_cremona_ellcurve-2005.11.03
 }}}
 or otherwise.
