+Kartongips - a kubecfg fork
+===========================
+
+This is Kartongips - a hscloud-specific kubecfg fork. It aims to let us implement features like:
+
+ - secret management
+ - multi-cluster support
+ - persistent diff-against-production (a.k.a. 'ultrakubediff').
+
+Fork technicalities
+-------------------
+
+We forked off from github.com/q3k/kubecfg at commit b6817a94492c561ed61a44eeea2d92dcf2e6b8c0.

+MakeUniversalImporter creates an importer that handles resolving imports from the filesystem and HTTP/S.
+
+In addition to the standard importer, supports:
+ - URLs in import statements
+ - URLs in library search paths
+
+A real-world example:
+ - You have https://raw.githubusercontent.com/ksonnet/ksonnet-lib/master in your search URLs.
+ - You evaluate a local file which calls `import "ksonnet.beta.2/k.libsonnet"`.
+ - If the `ksonnet.beta.2/k.libsonnet`` is not located in the current working directory, an attempt
+ will be made to follow the search path, i.e. to download
+ https://raw.githubusercontent.com/ksonnet/ksonnet-lib/master/ksonnet.beta.2/k.libsonnet.
+ - Since the downloaded `k.libsonnet`` file turn in contains `import "k8s.libsonnet"`, the import
+ will be resolved as https://raw.githubusercontent.com/ksonnet/ksonnet-lib/master/ksonnet.beta.2/k8s.libsonnet
+ and downloaded from that location.
