Change <meta> tag by plugin?

[butterfly]

Hi

I have in HTML (oc-content/themes/bender/common/head.php) META tag like:

Code: [Select]

<meta name="robots" content="archive">
<meta name="robots" content="index, follow">

I want to change by plugin this "META" to:

Code: [Select]

<meta name="robots" content="noarchive">
<meta name="robots" content="noindex, nofollow">

Is it possible?
