+ * The basic design of the pbproxy code is as follows.
+ *
+ * When a client selects text, say from an xterm - we only copy it when the
+ * X11 Edit->Copy menu item is pressed or the shortcut activated. In this
+ * case we take the PRIMARY selection, and set it as the NSPasteboard data.
+ *
+ * When an X11 client copies something to the CLIPBOARD, pbproxy greedily grabs
+ * the data, sets it as the NSPasteboard data, and finally sets itself as
+ * owner of the CLIPBOARD.
+ *
+ * When an X11 window is activated we check to see if the NSPasteboard has
+ * changed. If the NSPasteboard has changed, then we set pbproxy as owner
+ * of the PRIMARY and CLIPBOARD and respond to requests for text and images.
+ *
+ * The behavior is now dynamic since the information above was written.
+ * The behavior is now dependent on the pbproxy_prefs below.
