Solve the following python programming problem given the following code:
def main() : 
    INFO = 'Verilog code parser' 
    VERSION = pyverilog.utils.version.VERSION 
    USAGE = 'Usage: python example_parser.py file ...' 
    def showVersion() : 
        print (INFO) 
        print (VERSION) 
        print (USAGE) 
        sys.exit () 
optparser = OptionParser () 
    optparser.add_option ('-v', '--version', action = 'store_true', dest = 'showversion', default = False, help = 'Show the version') 
    optparser.add_option ('-I', '--include', dest = 'include', action = 'append', default = [], help = 'Include path') 
    optparser.add_option ('-D', dest = 'define', action = 'append', default = [], help = 'Macro Definition') 
    (options, args) = optparser.parse_args () 
    filelist = args 
    if options.showversion : 
        showVersion () 
for f in filelist : 
        if (not os.path.exists (f)) : 
            raise IOError (('file not found: ' + f)) 
if (len (filelist) == 0) : 
        showVersion () 
(ast, directives) = parse (filelist, preprocess_include = options.include, preprocess_define = VERSION.define) 
    ast.show () 
    for (lineno, directive) in directives : 
        print (('Line %d : %s' % (lineno, directive))) 

    
    

    Fix the buggy line: (ast, directives) = parse (filelist, preprocess_include = options.include, preprocess_define = VERSION.define)

#Here is Python code to fix the buggy line: (ast, directives) = parse (filelist, preprocess_include = options.

(ast, directives) = parse (filelist, preprocess_include = options.include, preprocess_define = options.define)
