Split up a mysqldump file with multiple databases, by database

I've been working on a python script which splits one big dump file into small ones, one per database. It's name is dumpsplit and here's a scratch:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
import re
import os

HEADER_END_MARK = '-- CHANGE MASTER TO MASTER_LOG_FILE'
FOOTER_BEGIN_MARK = '\/\*\!40103 SET TIME_ZONE=@OLD_TIME_ZONE \*\/;'
DB_BEGIN_MARK = '-- Current Database:'

class Main():
    """Whole program as a class"""

    def __init__(self,file,output_path):
        """Tries to open mysql dump file to call processment method"""
        self.output_path = output_path
        try:
            self.file_rsrc = open(file,'r')
        except IOError:
            sys.stderr.write('Can\'t open %s '+file)
        else:
            self.__extract_footer()
            self.__extract_header()
            self.__process()

    def __extract_footer(self):
        matched = False
        self.footer = ''
        self.file_rsrc.seek(0)
        line = self.file_rsrc.next()
        try:
            while line:
                if not matched:
