Solve the following python programming problem given the following code:
def read_config(config_path) : 
    cfg = DefaultConfigParser () 
    with open (config_path) as f : 
        if hasattr (cfg, 'read_file') : 
            cfg.read_file (f) 
else : 
            cfg.readfp (f) 
current_dir = os.path.dirname (config_path) 
    includes = [] 
    def _scan(filename, includes) : 
        if (os.path.abspath (filename) != filename) : 
            filename = os.path.join (current_dir, filename) 
paths = glob.glob (filename) 
        if (paths == []) : 
            logger.warn (('%r does not lead to any config. Make sure include paths are relative to the main config file' % filename)) 
includes += paths 
for include_file in cfg.dget ('circus', 'include', '').split () : 
        _scan (include_file, _scan) 
for include_dir in cfg.dget ('circus', 'include_dir', '').split () : 
        _scan (os.path.join (include_dir, '*.ini'), includes) 
logger.debug (('Reading config files: %s' % includes)) 
    return (cfg, ([config_path] + cfg.read (includes)))
