=head1 NAME
Mobile::Ads::Zestadz - module to serve Zestadz ads
Version 0.1.0
=head1 SYNOPSIS
use Mobile::Ads::Zestadz([$parent]);
$ad = new Mobile::Ads::Zestadz
($text,$link,$image) = $ad->get_zestadz_ad({
site => 'AdMob site code',
remote => $ENV{'HTTP_USER_AGENT'},
address => $ENV{'REMOTE_ADDR'},
text => 'default ad text',
link => 'default ad link',
test => 'set this if this is a test ad',
});
=head1 DESCRIPTION
C<Mobile::Ads::Zestadz> provides an object oriented interface to serve advertisements
from AdMob in mobile sites.
This was ported from VB code in their site
=head1 new Mobile::Ads::Zestadz
=over 4
=item [$parent]
To reuse Mobile::Ads in multiple (subsequent) ad requests, you can pass a C<Mobile::Ads>
reference here. Instead of creating a new Mobile::Ads object, we will use the one you
pass instead. This might save a little C<LWP::UserAgent> creation/destruction time.
=head2 Parameters/Properties
=over 4
=item site
C<>=> Zestadz site code, delivered by them. Something in the form off ``01234abcdef12345''
=item remote
C<>=> Remote User Agent ($ENV{'HTTP_USER_AGENT'}). In fact $ENV{'HTTP_USER_AGENT'} will be used
if not supplied.
=item address
C<>=> $ENV{'REMOTE_ADDR'}. All things about HTTP_USER_AGENT also apply here.
=item text
C<>=> Should we fail to retrieve a real ad, this is the text of the ad displayed instead
=item link
C<>=> Same with text, but for the ad's link.
