Application
    surfaceConvert
 
Description
    Converts from one surface mesh format to another.
 
Usage
    - surfaceConvert 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 -group \n
    Orders faces by region
 
Note
    The filename extensions are used to determine the file format type.
