=head1 NAME
Bio::Tools::Run::EMBOSSacd - class for EMBOSS Application qualifiers
=head1 SYNOPSIS
  # Get an EMBOSS factory
  use Bio::Factory::EMBOSS;
  $f = Bio::Factory::EMBOSS -> new();
  # Get an EMBOSS application  object from the factory
  $water = $f->program('water') || die "Program not found!\n";
  # Here is an example of running the application - water can
  # compare 1 sequence against 1 or more sequences using Smith-Waterman.
  # Pass a Sequence object and a reference to an array of objects.
  my $wateroutfile = 'out.water';
  $water->run({-asequence => $seq_object,
               -bsequence => \@seq_objects,
               -gapopen   => '10.0',
               -gapextend => '0.5',
               -outfile   => $wateroutfile});
  # Now you might want to get the alignment
  use Bio::AlignIO;
  my $alnin = Bio::AlignIO->new(-format => 'emboss',
                                -file   => $wateroutfile);
  while ( my $aln = $alnin->next_aln ) {
      # process the alignment -- these will be Bio::SimpleAlign objects
  }
=head1 DESCRIPTION
The EMBOSSacd represents all the possible command line arguments that
can be given to an EMBOSS application.
Do not create this object directly. It will be created and attached to
its corresponding Bio::Tools::Run::EMBOSSApplication if you set
  $application->verbose > 0
Call
  $application->acd
to retrive the Bio::Tools::Run::EMBOSSApplication::EMBOSSacd object.
See also L<Bio::Tools::Run::EMBOSSApplication> and L<Bio::Factory::EMBOSS>.
=head1 FEEDBACK
=head2 Mailing Lists
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to the
Bioperl mailing lists  Your participation is much appreciated.
  bioperl-l@bioperl.org                  - General discussion
  http://bioperl.org/wiki/Mailing_lists  - About the mailing lists
=head2 Support
Please direct usage questions or support issues to the mailing list:
I<bioperl-l@bioperl.org>
rather than to the module maintainer directly. Many experienced and
reponsive experts will be able look at the problem and quickly
address it. Please include a thorough description of the problem
with code and data examples if at all possible.
=head2 Reporting Bugs
report bugs to the Bioperl bug tracking system to help us keep track
the bugs and their resolution.  Bug reports can be submitted via the
web:

=head2 new
 Title   : new
 Usage   : $emboss_prog->acd($prog_name);
 Function: Constructor for the class.
           Calls EMBOSS program 'acdc', converts the
           HTML output into XML and uses XML::Twig XML
           parser to write out a hash of qualifiers which is
           then blessed.
