ODB is an object-relational mapping (ORM) system for C++. It provides tools, APIs, and library support that allow you to persist C++ objects to a relational database (RDBMS) without having to deal with tables, columns, or SQL and without manually writing any of the mapping code. For more information see: http://www.codesynthesis.com/products/odb/ This package contains the tracer ODB runtime library. The tracer runtime is only used for testing the ODB system and is not normally link to user applications. In most cases you will only need to build this library if you plan to build the ODB test suite. See the NEWS file for the user-visible changes from the previous release. See the LICENSE file for distribution conditions. See the INSTALL file for prerequisites and installation instructions.
