This document will help you generate flamegraphs for your node processes on OS X.
You can read about the various types of flamegraphs and how they are useful
in Brendan Gregg's wonderful write up here.
By the end of this document, you should have a flamegraph for you node app to play with.
# Hello, and welcome to makefile basics. | |

# You will learn why `make` is so great, and why, despite its "weird" syntax, | |
# it is actually a highly expressive, efficient, and powerful way to build | |
# programs. | |
