Creating a plugin function to remove or modify code

[nvinanda]

Hello,

I'm trying to create a plugin to remove a certain code from the footer of backend panel. I have seen the plugin creation tutorial at http://get-simple.info/wiki/plugins:creation and the given "hello world" example is good.

Now I'm trying to remove a few code like Support and Share links in the backend footer. The given example is good for adding new code but doesn't help in further modifications.
