How do I render a jQuery.tmpl Template to a String?

The documentation for jquery.tmpl uses .appendTo to insert the template into the DOM during the rendering process:

$.tmpl( myTemplate, myData ).appendTo( "#target" );

I am attempting to convert an existing app from another templating engine, and my code needs to render a template into a string first before it is added to the DOM. Is this possible? How would that be done?
