=head1 NAME
Bio::AlignIO::prodom - prodom sequence input/output stream
=head1 SYNOPSIS
Do not use this module directly. Use it via the L<Bio::AlignIO> class.
=head1 DESCRIPTION
This object can transform L<Bio::Align::AlignI> objects to and from prodom flat
file databases.
=head1 FEEDBACK
=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:

=head1 APPENDIX
The rest of the documentation details each of the object
methods. Internal methods are usually preceded with a _

use base qw(Bio::AlignIO);
=head2 next_aln
Title : next_aln
Usage : $aln = $stream->next_aln()
Function: returns the next alignment in the stream.
Returns : L<Bio::Align::AlignI> object
Args : NONE
=cut

=head2 write_aln
Title : write_aln
Usage : $stream->write_aln(@aln)
Function: writes the $aln object into the stream in prodom format ###Not yet implemented!###
Returns : 1 for success and 0 for error
Args : L<Bio::Align::AlignI> object
