26 * This is a simple GNOME SSH passphrase grabber. To use it, set the
27 * environment variable SSH_ASKPASS to point to the location of
28 * gnome-ssh-askpass before calling "ssh-add < /dev/null".
29 *
30 * There is only two run-time options: if you set the environment variable
31 * "GNOME_SSH_ASKPASS_GRAB_SERVER=true" then gnome-ssh-askpass will grab
32 * the X server. If you set "GNOME_SSH_ASKPASS_GRAB_POINTER=true", then the
33 * pointer will be grabbed too. These may have some benefit to security if
34 * you don't trust your X server. We grab the keyboard always.
