+# Nix package for GNUnet development
+#
+## INSTALL
+#
+# To build and install the package in the user environment, use:
+#
+# $ nix-env -f . -i
+#
+## BUILD ONLY
+#
+# To build the package and add it to the nix store, use:
+#
+# $ nix-build
+#
+## SHELL
+#
+# To launch a shell with all dependencies installed in the environment, use one of the following:
+#    $ nix-shell
+#
+# After entering nix-shell, build it:
+#
+# $ configurePhase
+# $ buildPhase
+#
+## NIXPKGS
+#
+# For all of the above commands, nixpkgs to use can be set the following way:
+#
+# a) by default it uses nixpkgs pinned to a known working version
+#
+# b) use nixpkgs from the system:
+#    --arg pkgs 0
+#
+# c) use nixpkgs at a given path
+#    --args pkgs /path/to/nixpkgs
+#

+      GNUnet is a framework for secure peer-to-peer networking that
+      does not use any centralized or otherwise trusted services.  A
+      first service implemented on top of the networking layer
+      allows anonymous censorship-resistant file-sharing.  Anonymity
+      is provided by making messages originating from a peer
+      indistinguishable from messages that the peer is routing.  All
+      peers act as routers and use link-encrypted connections with
+      stable bandwidth utilization to communicate with each other.
+      GNUnet uses a simple, excess-based economic model to allocate
+      resources.  Peers in GNUnet monitor each others behavior with
+      respect to resource usage; peers that contribute to the
+      network are rewarded with better service.
