Some SAGEfunctionality depends on databases.
Some extra databases are available that extends this
functionality.
Download db-*.tar from
http://modular.fas.harvard.edu/SAGE/dist/db/
Place it in your SAGEdirectory.
Extract it:
tar xf db-*.tar
Note:
That's it! You don't have to do anything further after
decompressing the database in the SAGEdirectory. It is now ready
to use with SAGE. No further install is needed.
