The + source code is loaded from the file name *file*. The byte-code is written to + *cfile*, which defaults to *file* ``+`` ``'c'`` (``'o'`` if optimization is + enabled in the current interpreter). If *dfile* is specified, it is used as the + name of the source file in error messages instead of *file*. If *doraise* is + true, a :exc:`PyCompileError` is raised when an error is encountered while + compiling *file*. If *doraise* is false (the default), an error string is + written to ``sys.stderr``, but no exception is raised. + + +.. function:: main([args]) + + Compile several source files.
