# Prints build logs for failed derivations in quiet build mode (-Q).

# Usage:
#
-# set -o pipefail
-# nix-build ... -Q ... | whatsupnix [user@target[:port]]
+# nix-build ... -Q ... 2>&1 | whatsupnix [user@target[:port]]
+#
+# Exit Codes:
+#
+# 0 No failed derivations could be found. This either means there where
+# no build errors, or stdin wasn't nix-build output.
+#
+# 1 Usage error; arguments couldn't be parsed.
+#
+# 2 Build error; at least one failed derivation could be found.
