This template just calls Template:Babel and passes its parameters there.
Usage
{{Babel-N|1=userboxes}}
To specify a custom header, footer, or color add the parameters |header=HEADER (default: Wikipedia:Babel), |footer=FOOTER (default: Search user languages), and/or |color=COLOR (default: white). You may also use |align=left to cause the box to appear on the left side of the page rather than the default right.
Adding <td> between two boxes causes a new column to be started at that point.
