  A coarse HTML tables to CSV (Comma-Separated Values) converter.
  
  Syntax    : %s source.html
  
  Arguments : source.html is the HTML file you want to convert to CSV.
              By default, the file will be converted to csv with the same
              name and the csv extension (source.html -> source.csv)
              You can use * and ?.
  
  Examples   : %s mypage.html
             : %s *.html

  class html2csv(HTMLParser.HTMLParser):
      ''' A basic parser which converts HTML tables into CSV.
          Feed HTML with feed(). Get CSV with getCSV(). (See example below.)
          All tables in HTML will be converted to CSV (in the order they occur
          in the HTML file).
          You can process very large HTML files by feeding this class with chunks
          of html while getting chunks of CSV by calling getCSV().
          Should handle badly formated html (missing <tr>, </tr>, </td>,
          extraneous </td>, </tr>...).
          This parser uses HTMLParser from the HTMLParser module,
          not HTMLParser from the htmllib module.
          Example: parser = html2csv()
                   parser.feed( open('mypage.html','rb').read() )
                   open('mytables.csv','w+b').write( parser.getCSV() )

          Versions:
             2002-09-19 : - First version
             2002-09-20 : - now uses HTMLParser.HTMLParser instead of htmllib.HTMLParser.
                          - now parses command-line.
          To do:
              - handle <PRE> tags
              - convert html entities (&name; and &#ref;) to Ascii.
