#* This sub-Makefile is in charge of detecting the current platform *
#* It sets some variables accordingly. Namely : *
#* *
#* PLATFORM The detected platform. This will default to "ansi" if *
#* auto-detection fails. *
#* *
#* BUILD The configuration and system-specific directory. Usually *
#* 'freetype/config/$(PLATFORM)' but can be different when *
#* a specific compiler has been requested on the *
#* command line.. *
#* *
#* CONFIG_RULES The 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 *
#* *
#* You need to set the following variable(s) before calling it: *
#* *
#* TOP The top-most directory in the FreeType library source *
#* hierarchy. If not defined, it will default to '.' *
#* *
#****************************************************************************
# If TOP is not defined, default it to '.'

# Now, include each detection rules file found in a `config/<system>'
# directory..
#
#
# we define the BACKSLASH variable to hold a single back-slash character
# This is needed because a line like
#
# SEP := \
#
# does not work with GNU Make (the back-slash is interpreted as a line
# continuation). While a line like :
#
# SEP := \\
#
# really define $(SEP) as "\" on Unix, and "\\" on Dos and Windows !!
#
BACKSLASH := $(strip \ )

# The following targets are equivalent, with the exception that they use
# slightly different syntaxes for the `echo' command. This is due to
#
# std_setup: is defined for most platforms
# dos_setup: is defined for Dos-ish platforms like Dos, Windows & OS/2
