+ODB License Exception for build2 Software
+               Version 1.0
+
+1. Intent
+
+The intent of this License Exception is to allow the build2 software
+to use ODB without the "copyleft" restrictions that would normally be
+imposed by the GPL, the license under which ODB is distributed.
+
+Specifically, the intent is to allow you to use the original build2
+software in your open source or proprietary works without imposing
+any additional restrictions to the terms and conditions of the MIT
+license used by build2.
+
+If you wish to modify the build2 software in such a way that it requires
+changes to the persistent object model handled by ODB, you can continue
+enjoying the terms of this exception provided that you are prepared to
+release your modifications under MIT or another open source license
+and you obtain a separate license exception for your modifications from
+Code Synthesis Tools CC.
+
+While this exception is specific to build2, any open source software
+project licensed under a more liberal than the GPL license can obtain
+a similar exception free of charge by contacting Code Synthesis Tools CC.
+
+2. Definitions
+
+"Original Software" is the build2 software (including, but not limited
+to its bpkg and bdep components), Copyright (c) Code Synthesis Ltd,
+distributed under the terms of the MIT license, and available to any
+third party from:
+
+  https://build2.org
+
+"ODB-Extended Software" are any modifications to the Original Software
+that require additions or changes to the persistent object model of
+the Original Software that is handled by ODB.
+
+"Work Based on the Original Software" is any derivative work under the
+copyright law that is either based on the Original Software or any
+modified version of the Original Software that does not constitute
+ODB-Extended Software.
+
+"Work Based on the ODB-Extended Software" is any derivative work under
+the copyright law that is based on any modified version of the Original
+Software that constitutes ODB-Extended Software.
+
+3. Legal Terms and Conditions
+
+As a special exception to the terms and conditions of version 2 of the
+GPL you may use the ODB runtime libraries in Original Software and in
+Works Based on the Original Software and distribute the resulting works
+in object code or executable form and without making source code for
+such works available to any third party, provided that all of the
+following conditions are met:
+
+  a) Original Software was licensed as a whole at no charge to all third
+     parties under the terms of the MIT license.
+
+  b) The ODB runtime libraries in Works Based on the Original Software
+     are used solely for the purpose of supporting the functionality of
+     the Original Software.
+
+The same exception does not apply automatically to ODB-Extended Software
+or Works Based on the ODB-Extended Software. If you wish to enjoy this
+exception for such works, then you will need to license ODB-Extended
+Software at no charge to all third parties under the terms of the MIT
+license or another open source license. You will also need to obtain a
+separate License Exception for ODB-Extended Software from Code Synthesis
+Tools CC.
