|  | Welcome to sstate cache management utilities. | 
|  | sstate-cache-management.sh <OPTION> | 
|  |  | 
|  | Options: | 
|  | -h, --help | 
|  | 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. | 
|  |  | 
|  | --extra-archs=<arch1>,<arch2>...<archn> | 
|  | Specify list of architectures which should be tested, this list | 
|  | will be extended with native arch, allarch and empty arch. The | 
|  | script won't be trying to generate list of available archs from | 
|  | AVAILTUNES in tune files. | 
|  |  | 
|  | --extra-layer=<layer1>,<layer2>...<layern> | 
|  | Specify the layer which will be used for searching the archs, | 
|  | it will search the meta and meta-* layers in the top dir by | 
|  | default, and will search meta, meta-*, <layer1>, <layer2>, | 
|  | ...<layern> when specified. Use "," as the separator. | 
|  |  | 
|  | This is useless for --stamps-dir or when --extra-archs is used. | 
|  |  | 
|  | -d, --remove-duplicated | 
|  | Remove the duplicated sstate cache files of one package, only | 
|  | the newest one will be kept. The duplicated sstate cache files | 
|  | of one package must have the same arch, which means sstate cache | 
|  | files with multiple archs are not considered duplicate. | 
|  |  | 
|  | Conflicts with --stamps-dir. | 
|  |  | 
|  | --stamps-dir=<dir1>,<dir2>...<dirn> | 
|  | Specify the build directory's stamps directories, the sstate | 
|  | cache file which IS USED by these build diretories will be KEPT, | 
|  | other sstate cache files in cache-dir will be removed. Use "," | 
|  | as the separator. For example: | 
|  | --stamps-dir=build1/tmp/stamps,build2/tmp/stamps | 
|  |  | 
|  | Conflicts with --remove-duplicated. | 
|  |  | 
|  | -L, --follow-symlink | 
|  | Remove both the symbol link and the destination file, default: no. | 
|  |  | 
|  | -y, --yes | 
|  | Automatic yes to prompts; assume "yes" as answer to all prompts | 
|  | and run non-interactively. | 
|  |  | 
|  | -v, --verbose | 
|  | Explain what is being done. | 
|  |  | 
|  | -D, --debug | 
|  | Show debug info, repeat for more debug info. |
