=head1 NAME

Mail::ListDetector::Detector::AutoShare - AutoShare message detector

=head1 SYNOPSIS

  use Mail::ListDetector::Detector::AutoShare;

=head1 DESCRIPTION

An implementation of a mailing list detector, for AutoShare mailing lists,
AutoShare is a freeware Macintosh list server by Mikael Hansen, see
http://home.comcast.net/~autoshare/autoshare/ for details about AutoShare.

Some AutoShare mailing list messages are RFC2919 compliant and all are RFC2369
compliant but this module provides more information.

=head1 METHODS

=head2 new()

Inherited from Mail::ListDetector::Detector::Base.

=head2 match()

Accepts a Mail::Internet object and returns either a
Mail::ListDetector::List object if it is a post to a AutoShare
mailing list, or C<undef>.

Since later version of AutoShare specifies a (mostly) unique ID for a mailing
list in the format of RFC2919, Mail::ListDetector::Detector::RFC2919 is used
to attempt to extract this information about the list.

=head1 BUGS

No known bugs.
