A script to clean obsolete sstate cache files
There would be many obsolete cache files in the SSTATE_DIR after several builds, this script can remove the obsolete one for a pkg, only leave the up to date one. Here is the help text: sstate-cache-management.sh <OPTION> Options: --help, -h Display this help and exit. --cache-dir=<sstate cache dir> Specify sstate cache directory, will use the environment variable SSTATE_CACHE_DIR if it is not specified. --remove-duplicated Remove the duplicated sstate cache files of one package, only the newest one would be kept.
