Environment management is an essential function in any complex, mission-critical system. Unfortunately, environment management is often overlooked and, even when addressed, usually only handled in the simplest way.

One of GNU make's many features allows you to shorten build times by running more than one command at a time. If your dependencies are all correct, or nearly correct, this can give you a significant improvement, and since it's built into the tool you get it "for free."

The worst of these is that GNU make parallel builds can produce incorrect results if the build dependencies are not sufficiently correct.
