/**************************************************************************/ /* Userscript to add a QR code display option to toolbar /* /* Generates a QR code image using the current Wikipedia page URL. /* Demo version so use at your own risk! /* /* Initial failure to display in the Toolbox may be due to: /* . needing to purge the page cache /* . or you may be on a page without "What links here" /* . the order of javascript changes might stop the link being added. If you /*  have 'addOnloadHook', it may need to run there rather than earlier. /* /* Link: http://enwp.org/User:Fæ/QRcode.js /* More info on QR codes: http://enwp.org/QR_code /* Created: 2 Feb 2011 /**************************************************************************/
