Examples
--------

./build.d clean # remove all generated files
./build.d generated/linux/release/64/dmd.conf
Important variables:
--------------------
HOST_DMD: Host D compiler to use for bootstrapping
AUTO_BOOTSTRAP: Enable auto-boostrapping by downloading a stable DMD binary
MODEL: Target architecture to build for (32,64) - defaults to the host architecture
Build modes:
------------
BUILD: release (default) | debug (enabled a build with debug instructions)
Opt-in build features:
ENABLE_RELEASE: Optimized release built
ENABLE_DEBUG: Add debug instructions and symbols (set if ENABLE_RELEASE isn't set)
ENABLE_LTO: Enable link-time optimizations
ENABLE_UNITTEST: Build dmd with unittests (sets ENABLE_COVERAGE=1)
ENABLE_PROFILE: Build dmd with a profiling recorder (D)
ENABLE_COVERAGE Build dmd with coverage counting
ENABLE_SANITIZERS Build dmd with sanitizer (e.g. ENABLE_SANITIZERS=address,undefined)
Targets

D build dependencies
====================
The strategy of this script is to emulate what the Makefile is doing.
Below all individual dependencies of DMD are defined.
They have a target path, sources paths and an optional name.
When a dependency is needed either its command or custom commandFunction is executed.
A dependency will be skipped if all targets are older than all sources.
This script is by default part of the sources and thus any change to the build script,
will trigger a full rebuild.
