"""
    12_to_13.py - converting CRLF / LF style to the future standard
    Use this to convert from 1.3 pre patch-275 to patch-275.
    
    Changes:
    * use OS style for logs (== no change, same as it was)
    * use CRLF for page files on any platform (text/* mandates it!) -
      and we will use that MIME type soon.
    * use LF only internally in moin, convert from/to CRLF early/late
      where needed
