=head1 NAME
Bio::TreeIO::nexml - A TreeIO driver module for parsing NeXML tree files
=head1 SYNOPSIS
use Bio::TreeIO;
my $in = Bio::TreeIO->new(-file => 'data.nexml' -format => 'Nexml');
while( my $tree = $in->next_tree ) {
}
=head1 DESCRIPTION
This is a driver module for parsing tree data in a NeXML format. For
more information on NeXML, visit L<http://www.nexml.org>.
=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 list. Your participation is much appreciated.
