#**************************************************************************
#*
#*  FreeType demo utilities sub-Makefile
#*
#*  This Makefile is to be included by "freetype/demo/Makefile". Its
#*  purpose is to compile MiGS (the Minimalist Graphics Subsystem)
#*
#*  It is written for GNU Make. Other make utilities are not
#*  supported.. !!
#*
#*
#*  The following variables must be defined :
#*
#*  CFLAGS     : C flags to use when compiling the utilities. This
#*               must NOT include the '-c' flag used to specify a
#*               simple compilation.
#*
#*  IFLAG      : include path flag. This is typically "-I" but some
#*               compilers use a different convention..
#*
#*  LFLAG      : add link directory flag. Usually '-L' but could be
#*               different..
#*
#*  OBJ_DIR    : target location of the object files
#*
#*  UTIL_DIR   : location of the utilities sources. I.e. this
#*               directory (usually "freetype/demo/graph").
#*
#*
#*  It also defines the following variables
#*
#*  SIMPLE_UTILS : list of object files for the non-graphical utilities
#*
#*  GRAPH_UTILS  : all object files, including the graphics sub-system
#*
#*  GRAPH_FLAGS  : additional compile flags for graphical apps
#*  GRAPH_LINK   : additional link flags for graphical apps
#*

# to indicate how to make a library file, but for now, I'll stick to
# unix, Win32 and OS/2-gcc..
