Google Code-in

The popular wiki platform, MediaWiki, powers a wide range of collaborative editing projects, such as Wikipedia and Wikivoyage, as well as many internal corporate wikis and other sites.

The importDump.php maintenance script is run from the command line to import an XML dump into the wiki. Your task is to add a --prefix parameter to this script, so that pages can be imported as subpages of a given root page. (For example, if the dump contains pages Apple and Banana, I could supply the parameter --prefix Fruit/ so that the pages are imported to Fruit/Apple and Fruit/Banana.) The value of this parameter should be required to end in /
