Javascript Plugin for Webpage

[Greg Scharlemann]

Does anyone know a source to find out more information about how to
setup a javascript plugin similar to Google Adsense? Thanks in
advance!

Google looks like:
<script type="text/javascript"><!--
google_ad_client = "pub-234234234234";
google_ad_width = 728;
google_ad_height = 90;
google_ad_format = "728x90_as";
google_ad_type = "text";
google_ad_channel = "";
google_color_border = "CCCCCC";
google_color_bg = "FFFFFF";
google_color_link = "FF9900";
google_color_text = "000000";
google_color_url = "000000";
//--></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

or Digg:
<script>
digg_url = 'URLOFSTORY';
</script>
