-"""
-This should only be run on a native Cell machine.  E.g., ps3, qs21, etc.
-
-It makes a few modifications to the file system and some pseudo shared libs
-so that cross compiling from a build machine over NFS works.  The changes
-do not harm local compilation.
-
-We create a symlink from /mnt/cell-root that points to /
-This allows the local and build machine to access the root filesystem
-using a common name, /mnt/cell-root.  This is required because
-configure hardcodes absolute paths into the generated Makefiles.
-
-There are some .so files that aren't really shared libraries, but rather are
-ascii linker scripts containing instructions to the linker.  Most of them
-contain a GROUP directive that includes hard-coded paths relative to /.
-We modify those files such that the hard-coded paths are relative to /mnt/cell-root
-instead of /.  This allows them to work locally and while cross compiling over NFS.
-
-E.g., /usr/lib/libc.so originally contains:
-
-    /* GNU ld script
-       Use the shared library, but some functions are only in
-       the static library, so try that secondarily.  */
-    OUTPUT_FORMAT(elf32-powerpc)
-    GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a  AS_NEEDED ( /lib/ld.so.1 ) )
-
-We modify it such that it reads:
-
-    /* GNU ld script
-       Use the shared library, but some functions are only in
-       the static library, so try that secondarily.  */
-    OUTPUT_FORMAT(elf32-powerpc)
-    GROUP ( /mnt/cell-root/lib/libc.so.6 /mnt/cell-root/usr/lib/libc_nonshared.a  AS_NEEDED ( /mnt/cell-root/lib/ld.so.1 ) )
-
-We backup <foo>.so to <foo>.so.original
