  # load available filters into memory
  my $filter = SWISH::Filter->new;


my $real_path="/vos/spain/test.pdf";

  # convert a document

  my $doc = $filter->convert(
        document     => \$real_path,  # path or ref to a doc
        content_type => 'application/pdf', # content type if doc refer
+ence
        name         => 'ela',    # optional name for this file (usefu
+l for debugging)
        user_data    => $whatever,     # optional data to make availab
+le to filters
   );

  return unless $doc;  # empty doc, zero size, or no filters installed

  # Was the document converted by a filter?
  my $was_filtered = $doc->was_filtered;

  # Skip if the file is not text
  return if $doc->is_binary;

  # Print out the doc
  my $doc_ref = $doc->fetch_doc;
  print $$doc_ref;

  # Fetch the final content type of the document
  my $content_type = $doc->content_type;

  # Fetch Swish-e parser type (TXT*, XML*, HTML*, or undefined)
  my $doc_type = $doc->swish_parser_type;
