=head1 NAME
GnuPG::UserId - GnuPG User ID Objects
=head1 SYNOPSIS
# assumes a GnuPG::PublicKey object in $publickey
my $user_id = $publickey->user_ids_ref->[0]->as_string;
=head1 DESCRIPTION
GnuPG::UserId objects are generally not instantiated on their
own, but rather as part of GnuPG::PublicKey or GnuPG::SecretKey
objects.
=head1 OBJECT METHODS
=over 4
=item new( I<%initialization_args> )
This methods creates a new object. The optional arguments are
initialization of data members;
=item compare( I<$other>, I<$deep> )
Returns non-zero only when this User ID is identical to the other
GnuPG::UserID. If $deep is present and non-zero, the User ID's
signatures and revocations will also be compared.
=back
=head1 OBJECT DATA MEMBERS
=over 4
=item as_string
A string of the user id.
=item validity
A scalar holding the value GnuPG reports for the trust of authenticity
(a.k.a.) validity of a key.
See GnuPG's DETAILS file for details.
=item signatures
A list of GnuPG::Signature objects embodying the signatures
on this user id.
=item revocations
A list of revocations associated with this User ID, stored as
GnuPG::Signature objects (since revocations are a type of
certification as well).
