>From 4ce174f3c72367fed945fb4448e294d205b8d88a Mon Sep 17 00:00:00 2001 From: Akira Yokosawa <akiysw@xxxxxxxxx> Date: Tue, 3 May 2016 00:01:16 +0900 Subject: [RFT PATCH 5/5] Make default target of Makefile overridable This commit adds a conditional assignment in Makefile so that the default target can be overridden by an environment variable. If you have the environment vairable "PERFBOOK_DEFAULT" set, its value will be regarded as the default target. Otherwise, perfbook.pdf is the default as before. This commit also updates FAQ.txt to add explanation of the environment variable.
