How to remove the tag meta generator" in joomla 1.7 and joomla 2.5?

Some time we want to remove the tag joomla 1.5 ,Joomla 1.7 orjoomla 2.5. I found some ways to do that.

First, you can edit the joomla core file: : \libraries\joomla\document\html\renderer \ head.php at line 91

Finally you can edit at index.php in the template that you use. Please find this line:

1.code="">include type="head" />

And add this just above: setMetaData('generator','my site'); ?>

and finally you have

1.$this->setMetaData('generator','my site'); ?>

2."head" />

In some template, it is in the header blog and maybe in header.php. In template of T3, it is in plugins\system\jat3\jat3\base-themes\default\blocks ... Find this could be difficult for you, but i will help you understand more your template and it good for you in further development.
