New description:

 eclib has changed a lot since the last upgrade, mostly in parts which do
 not affect Sage much, but there are exceptions, for example the handling
 of bounds in saturation for elliptic curves over Q (see #10840).

 As well as various changes in the source code, the new distribution in the
 new spkg now uses autotools throughout which should make building on
 different systems easier.

 After installing it (and before "sage -b") apply the patch also.

 '''spkg''':
 
[http://homepages.warwick.ac.uk/staff/J.E.Cremona/ftp/progs/eclib-20120428.spkg]

Comment (by leif):

 Replying to [comment:151 cremona]:
 > It's a tiny bug fix in something not used in Sage, and as the target has
 moved to 5.1 I thought I would change the spkg.  Sorry if that causes more
 work in testing.

 > I'm finding it very hard to edit trac tickets since the version was
 changed, especially on a netbook while travelling.  I only see one place
 on the ticket where the spkg name is given, in the Description, and I
 changed that.  If there's another one somewhere (why would there be two?)
 and you can change it to match, please do.

 No, but in the description we currently again have a link target different
 to its name:
 {{{
 '''spkg''':
 [http://homepages.warwick.ac.uk/staff/J.E.Cremona/ftp/progs/eclib-20120421.spkg
 //homepages.warwick.ac.uk/staff/J.E.Cremona/ftp/progs/eclib-20120428.spkg]
 }}}

 It's sufficient to just use
 {{{
 '''spkg''':
 
[http://homepages.warwick.ac.uk/staff/J.E.Cremona/ftp/progs/eclib-20120428.spkg]

 }}}
 (where the brackets are optional if you don't specify an [alternate] name
 for the link, but I always use them).

 Made that change, although technically the new spkg would need new review.
