        g2o is an open-source C++ framework for optimizing graph-based nonlinear 
        error functions. g2o has been designed to be easily extensible to a wide 
        range of problems and a new problem typically can be specified in a few 
        lines of code. The current implementation provides solutions to several 
        variants of SLAM and BA."""
