It's shorthand for outputting a value. It's the same as:

<? echo $head_script; ?>

it switches to php, then echoes out the value of the $head_script variable, then switches back to html.

It's called the "short echo tag."  Contrast the "short open tag" which you do not want to use because it is configuration-dependent and may cause confusion with XMLdocuments.  The short echo tag can be used rather easily to embed a PHP value in an HTML document.  See also the HEREDOC string.

I agree with you, gr8gonzo, you should have shared the points.  I used to request attention myself when this happened to someone else, and suggest sharing the points, but the last time I did that, the mod took all the points away from me and gave them all to the other person, so I refuse to be generous again.  I suggest you do it ... :)
