-/**
- * Utility function used by drivers to test the verions of other components.
- *
- * \param driver_name  Name of the driver.  Used in error messages.
- * \param driActual    Actual DRI version supplied __driCreateNewScreen.
- * \param driExpected  Minimum DRI version required by the driver.
- * \param ddxActual    Actual DDX version supplied __driCreateNewScreen.
- * \param ddxExpected  Minimum DDX minor and range of DDX major version required by the driver.
- * \param drmActual    Actual DRM version supplied __driCreateNewScreen.
- * \param drmExpected  Minimum DRM version required by the driver.
- * 
- * \returns \c GL_TRUE if all version requirements are met.  Otherwise,
- *          \c GL_FALSE is returned.
- * 
- * \sa __driCreateNewScreen, driCheckDriDdxDrmVersions2
- *
- * \todo
- * Now that the old \c driCheckDriDdxDrmVersions function is gone, this
- * function and \c driCheckDriDdxDrmVersions2 should be renamed.
