-#@ This script builds the (trusted) cross toolchain for arm.
-#@ It must be run from the native_client/ directory.
-#@
-#@ The toolchain consists primarily of a jail with arm header and libraries.
-#@ It also provides additional tools such as QEMU.
-#@ It does NOT provide the actual cross compiler anymore.
-#@ The cross compiler is now comming straight from a debian package.
-#@ So there is a one-time step required for all machines using this TC.
-#@ Which is especially true for build-bots:
-#@
-#@  tools/llvm/trusted-toolchain-creator.armel.precise.sh  InstallCrossArmBasePackages
-#@
-#@
-#@  Generally this script is invoked as:
-#@  tools/llvm/trusted-toolchain-creator.armel.precise.sh <mode> <args>*
-#@  Available modes are shown below.
-#@
-#@
-#@ This Toolchain was tested with Ubuntu Lucid
-#@
-#@ Usage of this TC:
-#@  compile: arm-linux-gnueabi-gcc -march=armv7-a -isystem ${JAIL}/usr/include
-#@  link:    arm-linux-gnueabi-gcc -L${JAIL}/usr/lib -L${JAIL}/usr/lib/arm-linux-gnueabi
-#@                                 -L${JAIL}/lib -L${JAIL}/lib/arm-linux-gnueabi
-#@
-#@ Usage of QEMU
-#@  TBD
