+# 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 includes the rules found
+#   in `PROJECT/builds/detect.mk'.  They are in charge of detecting the
+#   current platform.
+#
+#   A summary of the detection is displayed, and the file `config.mk' is
+#   created in the current directory.
+#
+# - When invoked later, this Makefile includes the rules found in
+#   `config.mk'.  This sub-Makefile defines some system-specific variables
+#   (like compiler, compilation flags, object suffix, etc.), then includes
+#   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.
+
+
+# First of all, check whether we have `$(value ...)'.  We do this by testing
+# for `$(eval ...)' which has been introduced in the same GNU make version.
