/* Simply link to this script in your HTML document / ASP.NET page
/* This will inject presense support into the current content page
/* All you need to do to integrate with the presence awareness
/* is to make a call to LinkToInstantMessage, or GetOnlineStatusImage
/* You can also reference myStatus variable, or myContacts variable within your other scripts on the containing page
/* You can also determine if the presence ability is supported by checking the isSupported variable for a value of 1
