        the end of the section
@end itemize

The general syntax of the VVencode command line is:
@example
  vvencode [options] input-file [options] [output-file] [options]
@end example

There are two @dfn{parameters} and many optional @dfn{qualifiers}.  The
parameters are:

@table @code
  @item input-file

  @item output-file
@end table

The command qualifiers modify the behaviour of VVcode and are all optional.
Qualifiers may appear before, between or after the parameters.  The
qualifiers acceptable to VVencode are:

@table @code
  @item debug
        Write copious debugging output to the standard error device or to
        the log file if the @code{+log} qualifier was specified.  This
        qualifier would normally only be used when trying to report a
        @code{VVencode} problem and may indeed have been disabled for the
        version that you are using.
  @item encoding_table file-spec
        Read the encoding table to be used from the file @file{file-spec}.
        The file must contain the 64 characters to be used by
        @code{VVencode}.  If this qualifier is not specified, the default
        @code{VVencode} encoding table will be used.
  @item format file-format
        Explicitly specify the file format that should be assumed by
        @code{VVencode} when it is reading the input file.  The
        @code{file-format} value must be one of @samp{fixed}, @samp{stream}
        and @samp{variable}.  This qualifier would only be used if it was
        necessary to override the value determined automatically by
        VVencode.
  @item header_filespec file-spec

  @item help
        VVencode will display a usage message on the standard error device
        and exit.
  @item log file-spec

  @item mode file-mode
        Explicitly specify the file mode that should be assumed by
        @code{VVencode} when it is reading the input file.  The
        @code{file-format} value must be one of @samp{binary} and
        @samp{text}.  This qualifier would only be used if it was
        necessary to override the value determined automatically by
        VVencode.
  @item overwrite

  @item record_length

  @item split_size

  @item timestamp time

  @item translation_file file-spec

@end table
