# If run without arguments, the script asks for required arguments one
# by one, which includes the above two (--compiler and --build-type).
#
# Optional arguments include the version of compiler and additional
# build modifiers such as link-time-optimizations (--modifier lto),
# feedback-directed-optimizations (--modifier fdo), and taking advantage
# of the building-machine's full instructions sets (--modifier native).
# Optional arguments allow specifying the version of compiler,
# machine type, and applying build modifiers such as:
# - link-time-optimizations (--modifier lto),
# - feedback-directed-optimizations (--modifier fdo)
# - current processor instructions sets (--modifier native)
# All modifiers are available simulatenously.
