+# File: build-config
+# Purpose:
+#  This script serves the same purpose as ./configure in traditional
+#   autoconf setups.
+#  It takes build configuration options from command line, checks them,
+#  builds a config dictionary, augments it with some default and/or
+#  computed values and saves it to build/build-config.json
+#  for other build scripts to read.
