=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 one
of 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:

# You will need to enable the protpars program. This
# can be done in (at least) two ways:
#
# 1. define an environmental variable PHYLIPDIR:
# export PHYLIPDIR=/home/shawnh/PHYLIP/bin
#
# 2. include a definition of an environmental variable CLUSTALDIR in
# every script that will use Clustal.pm.
# $ENV{PHYLIPDIR} = '/home/shawnh/PHYLIP/bin';
#
# 3. You can set the path to the program through doing:
# my @params('program'=>'/usr/local/bin/protdist');
# my $protpars_factory = Bio::Tools::Run::Phylo::Phylip::ProtPars->new(@params);
#
