From 447fb74d97f0fecbfe363cda7760df231e9b4c27 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Wed, 10 Jan 2018 15:37:45 +0000 Subject: [PATCH] exp: remove exp/proxy and exp/terminal packages The exp/proxy package was removed from the master library in https://golang.org/cl/6461056 (August, 2012). The exp/terminal package was removed from the master library in https://golang.org/cl/5970044 (March, 2012). I'm not sure why they lingered in the gofrontend copy, but let's finally remove them now.
