ARM GCC toolchain

Hi - first off, thanks a ton for providing the pre-built toolchain at
http://www.mikrocontroller.net/articles/ARM_GCC_toolchain_for_Linux_and_Mac_OS_X.

I was wondering if there are any plans to update this with newer
versions of each of the components?  Or if not, has anybody created a
script to automate re-builds of the toolchain?  Thanks.
