2.0.0
       Removed -a option that did nothing.

       Removed -m option from rapper but it was never documented here.

       Removed -n option that was long hidden.

       Removed -s option that was equivalent to -f scanForRDF

   1.4.16
       Added  -I/--input-uri  and  -O/--output-uri to set the input and output (parser and serializer) base URIs
       separately.

   1.4.15
       Added -t/--trace to do URI traces.

   1.4.5
       Updated to add serializer rdfxml-abbrev

   1.4.3
       Updated potential parser and serializers and described -f for defining namespaces.

   1.3.0
       Added -f for features.
       Added -g for guessing the parser to use.

   1.1.0
       Removed -a, --assume since rdf:RDF is now always optional.

       The rapper utility allows parsing of RDF content by the Raptor RDF parser toolkit emitting the results as
       RDF  triples  in  a  choice  of syntaxes.  The INPUT-URI can be a file name, '-' for standard input or if
       Raptor is built with a WWW retrieval library, a general URI.  The optional INPUT-BASE-URI is used as  the
       document  parser  base  URI if present otherwise defaults to the INPUT-URI.  A value of '-' means no base
       URI.

       rapper - Raptor RDF parsing and serializing utility

       rapper uses the usual GNU command line syntax, with long  options  starting  with  two  dashes  (`-')  if
       supported by the getopt_long function.  Otherwise the short options are only available.

       -h,--help
              Show a summary of the options.

       -i,--inputFORMAT
              Set  the  input  FORMAT  to one of 'rdfxml' (RDF/XML, default), 'ntriples' (N-Triples, see below),
              'turtle' (Turtle, see below) or 'rss-tag-soup' (RSS Tag Soup).  The RSS Tag Soup parser  can  turn
              the many XML RSS formats, Atom 0.3 and Atom 1.0 into RDF triples.

              The list of parsers depends on how libraptor(3) was built.  The list of supported parsers is given
              in the help summary given by -h.

       -I,--input-uriURI
              Set the input/parser base URI or use value '-' for no base.  The default is the INPUT-URI argument
              value.

       -o,--outputFORMAT
              Set  the  output  FORMAT  to  'ntriples' (N-Triples, default), 'rdfxml' (RDF/XML), 'rdfxml-abbrev'
              (RDF/XML with abbreviations) or 'rss-1.0' (RSS 1.0, also an RDF/XML syntax).

              The list of serializers depends on how libraptor(3) was built.  The list of supported  serializers
              is given in the help summary given by -h.

       -O,--output-uriURI
              Set  the  output/serializer  base URI or use value '-' for no base.  The default is the input base
              uri, either set by the argument INPUT-BASE-URI or via options -I,--input-uriURI-c,--count
              Only count the triples and produce no other output.

       -e,--ignore-errors
              Ignore errors, do not emit the messages and try to continue parsing.

       -f,--featureFEATURE[=VALUE]
              Set a parser or serializer feature FEATURE to a value, or to 1 if VALUE is omitted, Use -f help to
              get lists of valid parser and serializer features.

              If the form -f 'xmlns:prefix="uri"' is used, the prefix and namespace uri given will  be  set  for
              serializing.  The syntax matches XML in that either or both of prefix or uri can be omitted.

       -g,--guess
              Guess the parser to use from the source-URI rather than use the -i FORMAT.

       -q,--quiet
              No extra information messages.

       -r,--replace-newlines
              Replace newlines in multi-line literals with spaces.

       --show-graphs
              Print  graph names (URIs) as they are seen in the input.  This only has a meaning for parsers that
              support graph names such as the TRiG parser.

       --show-namespaces
              Print namespaces as they are seen in the input.

       -t,--trace
              Print URIs retrieved during parsing.  Especially useful for monitoring what the  guess  and  GRDDL
              parsers are doing.

       -w,--ignore-warnings
              Ignore warnings, do not emit the messages.

       -v,--version
              Print the raptor version and exit.
