>Modules/main.cxx:SWIG_main()</tt> is the "real" main.  It
initializes the preprocessor and typemap machinery, defines some
preprocessor symbols, locates the SWIG library, processes common
command-line options, and then calls the language-specific command-line
parser.  From here there are three paths: "help", "checkout" and
everything else.
  <ul>
  <li> In "help" mode, clean up open files and exit.
  <li> In "checkout" mode, copy specified files from the SWIG library
       to the current directory.  Error
