  # This file is designed for GNU Make, do not use it with another Make tool!
  #
  # It works as follows:
  #
  # - When invoked for the first time, this Makefile will include the rules
  #   found in `PROJECT/builds/detect.mk'.  They are in charge of detecting
  #   the current platform.
  #
  #   A summary of the detection will be displayed, and the file `config.mk'
  #   will be created in the current directory.
  #
  # - When invoked later, this Makefile will include the rules found in
  #   `config.mk'.  This sub-Makefile will define some system-specific
  #   variables (like compiler, compilation flags, object suffix, etc.), then
  #   include the rules found in `PROJECT/builds/PROJECT.mk', used to build
  #   the library.
  #
  # See the comments in `builds/detect.mk' and `builds/PROJECT.mk' for more
  # details on host platform detection and library builds.
