=head1 NAME
Bio::Symbol::Alphabet - BSANE/BioCORBA compliant symbol list alphabet
=head1 SYNOPSIS
{
my $alphabet = Bio::Symbols::Alphabet->new(-symbols => [ @s ],
-subalphabets => [ @alphas ] );
my @symbols = $alphabet->symbols;
my @subalphas = $alphabet->alphabets;
if( $alphabet->contains($symbol) ) {
# do something
}
}
=head1 DESCRIPTION
Alphabet contains set of symbols, which can be concatenated to
form symbol lists. Sequence string, for example, is stringified
representation of the symbol list (tokens of symbols).
This module was implemented for the purposes of meeting the
BSANE/BioCORBA spec 0.3 only.
=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.

=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
