+# Toolchain rules for building libraries
+#
+# Support multi-platform builds
+# You may define PLATFORM=.. prefix for compiler
+# if PLATFORM is defined it will owerride CC and AR
+# You may also specify CC and AR separately.
+# example: Compile with KEIL
+# make CC=ArmCC AR=ArmAR
+#
+# example: Cross Compile with Gnu toolchain, for embedded Linux
+# make PLATFORM=arm-linux-gnueabi-
+#
+# Special rules for IAR-ARM toolchains added, AR tool on that does not follow common arquements.
+# make CC=iccarm  uses iarchive.exe for creating a archive.
+#
+# Special rules for IAR-RL78 toolchain added, uses own AR and compiler requires specific flags
+# make CC=iccrl78
+#
+# When using ArmCC, Select CPU by defining one of following supported values
+#  CPU=Cortex-M0
+#  CPU=Cortex-M3
+#  CPU=Cortex-M4
+#
+# example:
+# make CC=armcc CPU=Cortex-M4
+
+#
+# If PLATFORM prefix is defined,
+# generate CC and AR accordingly
+#
