/* This user script allows the semiautomatic substitution of deleted userboxes on user talk pages.
To enable it, add the following line to [[Special:Mypage/monobook.js]]:

 {{subst:includejs | User:Ilmari Karonen/userboxes.js }}

You may also change the list of userboxes to be substed and the location they are substed from by assigning your own values to window.userboxRegExp and window.userboxPrefix.  These will override the default values below.

The format expected from the regexp is a list of userbox names, without the "Template:User_" prefix, separated by pipes as in "box1|box2|box3".  Most types of regexp syntax work as expected, but note that the regexp is postprocessed so that "." matches a literal period, and "_" and " " both match either a space or an underscore.  And don't forget to double any backslashes.
