#@ This script creates the mips trusted SDK.
#@ It must be run from the native_client directory.
+# This script is intended to build a mipsel-linux-gnu cross compilation
+# toolchain that runs on x86 linux and generates code for a little-endian,
+# hard-float, mips32 target.
+#
+# It expects the host machine to have relatively recent versions of GMP (4.2.0
+# or later), MPFR (2.4.2), and MPC (0.8.1) in order to build the GCC.
+#
+# Common way to get those is:
+# sudo apt-get install libmpfr-dev libmpc-dev libgmp3-dev
