Application
    surfaceMeshConvert

Description
    Converts from one surface mesh format to another

Usage
    - surfaceMeshConvert inputFile outputFile [OPTION]

    @param -clean \n
    Perform some surface checking/cleanup on the input surface

    @param -scale \<scale\> \n
    Specify a scaling factor for writing the files

    @param -triSurface \n
    Use triSurface library for input/output

    @param -keyed \n
    Use keyedSurface for input/output

Note
    The filename extensions are used to determine the file format type.
