+# This sub-Makefile is in charge of detecting the current platform. It sets
+# the following variables:
+#
+# BUILD_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.
