+// ContentSettingBubbleContents is used when the user turns on different kinds
+// of content blocking (e.g. "block images").  When viewing a page with blocked
+// content, icons appear in the omnibox corresponding to the content types that
+// were blocked, and the user can click one to get a bubble hosting a few
+// controls.  This class provides the content of that bubble.  In general,
+// these bubbles typically have a title, a pair of radio buttons for toggling
+// the blocking settings for the current site, a close button, and a link to
+// get to a more comprehensive settings management dialog.  A few types have
+// more or fewer controls than this.
