Saving a site as a template in SharePoint 2010

I often create sites in one environment and then want to recreate them in another. Easiest way I've found is to save the site as a template (remember to tick to include content) and then use the template on your new environment to create the site.

Problem is I can't find the 'Save site as template' link in SharePoint 2010. You need to reactive the 'Publishing' feature for your site, then the option reveals itself in 'Site actions' under 'Site settings'.
