+#*
+#*  FreeType build system - top-level Makefile
+#*
+#*  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 `freetype/config/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 `freetype/config/freetype.mk',
+#*    used to build the library.
+#*
+#*  See the comments in `config/detect.mk' and `config/freetype.mk' for
+#*  more details on host platform detection and library builds..
