-;;; Remember ongoing GNUnet downloads so as to be able to resume them
-;;; later.  Typical usage is to define the following alias in your
-;;; favorite shell:
-;;;
-;;;    alias gnunet-download='gnunet-download-manager.scm download'
-;;;
-;;; You may have a ~/.gnunet-download-manager.scm Scheme configuration
-;;; file.  In particular, if you would like to be notified of
-;;; completed downloads, you may want to add the following line to
-;;; your configuration file:
-;;;
-;;;   (add-hook! *completed-download-hook*
-;;;               completed-download-notification-hook)
-;;;
-;;; This script works fine with GNU Guile 1.6.4, and doesn't run with
-;;; Guile 1.4.x.

-;;; Enjoy!
