| # 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. |
| |

| # The variable TOP holds the path to the topmost directory in the FreeType |
| # engine source hierarchy. If it is not defined, default it to `.'. |

| # to be built, run the auto-detection rules to figure out which |
| # configuration rules file to use. |
| # |
| # Note that the configuration file is put in the current directory, which is |
| # not necessarily $(TOP). |
| |
| # If `config.mk' is not present, set `check_platform'. |
