+   <b>"RootBrowser" app</b><br><br>
+   This application is a simplified version of TBrowser and TCanvas for iOS. User can open ROOT's file (application uses TWebFile) and browse file's contents.<br>
+   RootBrower registeres *.root file extension in a system, so for example, attached root files from a mail client can be opened by RootBrowser.<br><br>
+   Application has several views. In a top level view, user can see opened files, open new files, close files (long press gesture on a file icon):<br><br>

+   </center>
+   <br><br>
+   Tap gesture on a file's icon will open "File contents" view. This view shows objects and nested directories. For objects small previews are<br>
+   generated. Tapping on a directory's icon will open new view with directory's contents. Simple search is supported (in the current TDirectoryFile).<br><br>
