/**
 vtkParseMain.h provides argument parsing for the wrapper executables.

 Usage: vtkWrap [options] infile ...

 -D <macro[=def]>  add a macro definition
 -U <macro>        cancel a macro definition
 -I <dir>          add an include directory
 -o <file>         specify the output file
 @<file>           read arguments from a file
 --help            print a help message and exit
 --version         print the VTK version number and exit
 --hints <file>    hints file
 --types <file>    type hierarchy file

 Notes:

 1) The "-o" option is needed when there are multiple input files.
    Otherwise, the output file can be given after the input file.

 2) The "@file" option allows arguments to be stored in a file,
    instead of given on the command line.  The use of such a file
    is sometimes necessary to avoid overflowing the 8191-character
    command-line limit on Windows.  If the file is not found, then
    "@file" will be passed as as a command-line parameter.
