Joomla: Why is the "Extension Manager" menu item not showing in the "Extensions" drop down menu?

Question

As per the title. I am running Joomla 2.5.

The only items visible in the "Extensions" drop down menu are:

• Module Manager
• Plug-in Manager
• Template Manager
• Language Manager

EDIT: I am doing this for the purpose of installing a template, as per the instructions on this page: http://docs.joomla.org/J2.5:Installing_a_template

As Elin's comment suggests, you must be a super user in order for this menu item to display.
