From 9dfa16fc057f4c07f79ae68a538e77e3ea21d498 Mon Sep 17 00:00:00 2001 From: Apollon Oikonomopoulos Date: Tue, 31 May 2011 15:50:28 +0300 Subject: [PATCH] Export instance tags to instance hooks Instance hooks now get an INSTANCE_TAGS environment variable, which contains a space-delimited list of the affected instance's tags. Also update the documentation to reflect the change.
