-# SQLBase7-SA
-
-SQLBase7-SA is a SQLAlchemy driver/dialect for the Centura SQLBase
-database, specifically version 7.5.1.
-
-## About the Project
-
-From what I can tell, SQLBase is still an actively-developed database,
-but it is no longer owned by Centura (see
-[here](http://en.wikipedia.org/wiki/Gupta_Technologies)).  Also, the
-current version (according to [this
-page](http://www.unify.com/Products/Data_Management/SQLBase/), as of
-25 Apr 2010) is 11.5, so I have no idea how useful this project will
-be for versions of SQLBase more recent than 7.5.1.
-
-This project exists only for the sake of providing read-only access to
-legacy data, specifically that used by the
-[CAM32](http://www.camcommerce.com/products/CAM32.aspx) Point of Sale
-software.  It's possible that it could allow writing data, etc., but I
-personally won't be adding any such features unless/until the need
-arises.
-
-I don't expect there to be much of anyone using SQLBase 7.5.1 at this
-point (besides perhaps other CAM32 users), but if you do happen to
-need additional functionality from this project or just have questions
-or comments, feel free to drop me a line at lance@edbob.org.
-
-## Downloads
-
-The code is released under the [GNU General Public
-License](http://www.gnu.org/licenses/gpl.html), version 3.
-
-It is available at [PyPI](http://pypi.python.org/pypi/SQLBase7-SA), so
-the easiest way to get the package is with the command:
-
-      # pip install SQLBase7-SA
-
-Again, this project is extremely specific to my needs, so I'm only
-building eggs for Python 2.5 and 2.6 at this point.  If you happen to
-need something else then please contact me.
