    """Import the xml file created by the smconv.pl script to Mnemosyne.
    smconv.pl is available at http://smconvpl.sourceforge.net and reads
    SuperMemo for Palm databases and exports them to XML.

    In order to import the generated XML into mnemosyne, care must be taken
    to ensure the correct charset encoding of the input file. In my case,
    the palm databases are "windows-1252". The xml file generated by smconv.pl
    was set to "us-ascii". This makes the XML parser fail. For me, changing
    the xml header to <?xml version="1.0" encoding="windows-1252"?>  worked
    well. However, your mileage may vary.

    Restrictions:

    - SM for Palm has six fields for each card. Templates can be used to
      format these fields and to control whether they are part of  the
      question or of the answer. However this class assumes that the first
      field is the question and the second field is the answer.
