-# Welcome to the top-level default.nix of stockholm.

-# You can discover the whole thing easily using the `get` utility,
-# which can be found at http://cgit.cd.krebsco.de/get/tree/get
-# To install `get` on any Nix-enabled system, use:
-#
-#     nix-env -f /path/to/stockholm -iA pkgs.get
-#
-# The "current" arguments are used to provide information about the user who's
-# evaluating this file.  This information is used to determine which user
-# namespace is to be used.  Of course there's nothing trying to prevent you
-# from forging this information.  E.g. you could try to generate the deployment
-# script for some random user's system, targeting some random host:
-#
-#     LOGNAME=tv get krebs.deploy system=nomic target=8.8.8.8
-#
