From 10265aa56b22ac4f04e7ba08330138e4507534e4 Mon Sep 17 00:00:00 2001 From: Joshua Haberman Date: Fri, 15 Jul 2011 12:05:43 -0700 Subject: Directory restructure. Includes are now via upb/foo.h. Files specific to the protobuf format are now in upb/pb (the core library is concerned with message definitions, handlers, and byte streams, but knows nothing about any particular serializationf format). --- src/upb.c | 122 -------------------------------------------------------------- 1 file changed, 122 deletions(-) delete mode 100644 src/upb.c (limited to 'src/upb.c') diff --git a/src/upb.c b/src/upb.c deleted file mode 100644 index 0f3ea18..0000000 --- a/src/upb.c +++ /dev/null @@ -1,122 +0,0 @@ -/* - * upb - a minimalist implementation of protocol buffers. - * - * Copyright (c) 2009 Google Inc.
