From 096c7e889f3b9bd42a81fb0216e2a68fb27159fc Mon Sep 17 00:00:00 2001 From: Michael Stahl Date: Fri, 14 Nov 2014 18:54:06 +0100 Subject: add a script to generate a dummy library to "build" all headers ... to be used together --with-iwyu to track down bloat in headers, which are not always named in the convention that include-what-you-use expects for reporting issues.
