I personally dislike Apple's "@2x" nomenclature for high-def images for iDevices. But we're stuck with it. The embedded at-sign confuses subversion unless you append the file name with an at-sign:% svn add bunnies@2x.png svn: warning: 'bunnies' not found % svn add bunnies@2x.png@ A bunnies@2x.png(thanks to Gus Mueller, Mike Ash, and Guy English)
