=head1 NAME
|

Net::Connection::Match::Protos - Runs a basic state check against a Net::Connection object.

=head1 METHODS
|
||||
|
||||
=head2 new
|
||||
|
||||
This intiates the object.
|
||||
|
||||
It takes a hash reference with one key. One key is required and
|
||||
that is 'protos', which is a array of protocols to match against.
|
||||
|
||||
Atleast one state must be present.
|
||||
|
||||
If the new method fails, it dies.

One argument is taken and that is a Net::Connection object.
