+# This sub-Makefile is in charge of detecting the current platform.  It sets
+# the following variables:
+#
+#   PLATFORM_DIR The configuration and system-specific directory.  Usually
+#                `builds/$(PLATFORM)' but can be different for custom builds
+#                of the library.
+#
+# The following variables must be defined in system specific `detect.mk'
+# files:
+#
+#   PLATFORM     The detected platform.  This will default to `ansi' if
+#                auto-detection fails.
+#   CONFIG_FILE  The configuration sub-makefile to use.  This usually depends
+#                on the compiler defined in the `CC' environment variable.
+#   DELETE       The shell command used to remove a given file.
+#   COPY         The shell command used to copy one file.
+#   SEP          The platform-specific directory separator.
+#   COMPILER_SEP The separator used in arguments of the compilation tools.
+#   CC           The compiler to use.
+#
+# You need to set the following variable(s) before calling it:
+#
+#   TOP_DIR      The top-most directory in the FreeType library source
+#                hierarchy.  If not defined, it will default to `.'.
+
+# Set auto-detection default to `ansi' resp. UNIX-like operating systems.
