+/* Package dialog provides a simple cross-platform common dialog API.
+Eg. to prompt the user with a yes/no dialog:
+
+     if dialog.MsgDlg("%s", "Do you want to continue?").YesNo() {
+         // user pressed Yes
+     }
+
+The general usage pattern is to call one of the toplevel *Dlg functions
+which return a *Builder structure. From here you can optionally call
+configuration functions (eg. Title) to customise the dialog, before
+using a launcher function to run the dialog.
