DOJO : Suppourted attributes in the script tag

[Ravi Kiran Va]

<script type="text/javascript" src="js/dojo/dojo/dojo.js"
djConfig="isDebug: true, parseOnLoad: true"></script>


On to the DOJO docs it tells that the isDebug , enables debug logging and messages . If this is set to true
Please tell me where exactly the logging and messages can be seen .

2nd Question :

This is about another attribute parseOnLoad , when this parseOnLoad is set to true , the docs of DOJO say that "parseOnLoad flag tells Dojo to scan the DOM for setup cues once the page has finished loading."

Can anybody please let me know what is the meaning of "Dojo to scan the DOM for setup cues" .
Thanks in advance .
