This reverts commit fd8249e99bcad0231e6ea65cd77c32aae9a54026. * Fixing some auto refactor strangeness and typo. * Making keys more human readable. --- vendor/github.com/alecthomas/log4go/config.go | 288 -------------------------- 1 file changed, 288 deletions(-) delete mode 100644 vendor/github.com/alecthomas/log4go/config.go (limited to 'vendor/github.com/alecthomas/log4go/config.go') diff --git a/vendor/github.com/alecthomas/log4go/config.go b/vendor/github.com/alecthomas/log4go/config.go deleted file mode 100644 index 577c3eb2f..000000000 --- a/vendor/github.com/alecthomas/log4go/config.go +++ /dev/null @@ -1,288 +0,0 @@ -// Copyright (C) 2010, Kyle Lemons .
