+# Toolchain wrapper script.
+#
+# This script allows us to use a small number of GCC / binutils cross-tools
+# (one toolchain per instruction set architecture) to implement a larger
+# number of processor- or board-specific tools.  The wrapper script is
+# configured at install time with information covering basic CFLAGS,
+# LD options and the toolchain triplet name.
