Several fixes: * We have put the sstate file to SSTATE_DIR/??/ currently, but the sstate file on the SSTATE_MIRRORS or the obsolete one is still in SSTATE_DIR/ (no subdir), update the script to support manage them. * Remove the related ".done" file in the SSTATE_DIR. * Add a "-L, --follow-symlink" which will remove both the symbol link and the destination file * Change the "ls -u file_list" (access time) to "ls -t file_list" (change tiem), since the "ls -u" and readlink will change the symlink's access time, which would make the result inconsistent. A solution is save the access time before every "ls -u" and "readlink", save it back after the command, but this would cause performance lost since it needs check each file and modify the symlink's status. Use the "-t" doesn't cause much different.

Poky
====
Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a
reference manual which can be found at:
http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.
