- * 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.
