-# The following environment variables can be used to configure the build:
-#
-# CC="compiler"
-# Specify the compiler to use.
-# By default, cc will be used.
-# The string "compiler" must be the name of an executable in $PATH.
-#
-# ARCH="architecture"
-# You can use this variable to build for a different architecture, for example
-# if you want to cross-compile or to use the portable version.
-# By default, the build script will detect which architecture it is running on.
-# The string "architecture" must be one of "AVX2", "NEON" or "PORTABLE".
-#
-# THREADS=n
-# The maximum number of threads to use for multi-threaded operations.
-# This is also used as default value in case an operation allows
-# specifying how many threads to use.
-# By default, 8 threads will be used (TODO: in the future this will be
-# determined base on the system).
-# The number n must be between 1 and 128.
-#
-# SANITIZE="option1,option2,..."
-# Add the options "-fsanitize=option1", "-fsanitize=option2", ... to the
-# compilation command when compiling in debug mode.
-# By default, no sanitizer is used.
-#
-# Examples
-#
-# 1. Build using clang and 4 threads
-#    CC=clang THREADS=4 ./configure.sh && make
-#
-# 2. Build using thread and undefined behavior sanitizers when in debug mode
-#    SANITIZE="thread,undefined" ./configure.sh && make
