Remove '-v' option from 'cp' command (GNUism) in database_cremona_ellcurve

[sagetrac-drkirkby]

The use of a non-POSIX option '-v' to the 'cp' command prevents this package installing on Solaris. The option, which can also be written as --verbose, is only to show what is actually being copied, so removing it should have no impact.
Therefore

cp -rv cremona $SAGE_DATA/

was changed to

cp -r cremona $SAGE_DATA/

in spkg-install.

I also renamed 'SAGE.txt' to SPKG.txt, and added a slightly better description, and upstream contact information, to make it more consistent with other packages.

This is an optional Sage package.

It is unusual in that the .spkg file, was a tar file, and not a compressed tar file as they usually are.

The updated files can be found at:

This is the case for all databases of compressed files. One makes a non-compressed spkg by doing

   sage -pkg_nc directory_name

Thank you for the information. I used 'tar' to create it, rather than Sage with any option. It seems to work for me. Perhaps you can test it and review it.

This looks fine to me. I read the changed files and also successfully installed it onto 4.2.1. I am happy to be the upstream contact (and would expect to be contacted if anyone found an error in the database). I should probably volunteer to be the spkg maintainer, but (embarrassingly) I do not even know the format of the main data file "cremona" in there! So in practice William is the maintainer. I will ask him to give me instructions....

It's just a Python pickle.
