+Purging Duplicate Shared State Cache Files
+-------------------------------------------
+
+After multiple build iterations, the Shared State (sstate) cache can contain
+duplicate cache files for a given package, while only the most recent one
+is likely to be reusable. The following command purges all but the
+newest sstate cache file for each package::
+
+ sstate-cache-management.sh --remove-duplicated
--cache-dir=build/sstate-cache
+
+This command will ask you to confirm the deletions it identifies.
+
+Note::
+
+ The duplicated sstate cache files of one package must have the same
+ architecture, which means that sstate cache files with multiple
+ architectures are not considered as duplicate.
+
+Run ``sstate-cache-management.sh`` for more details about this script.
+
Working with Packages
=====================
Did anyone have time to have a look at what I wrote ? There may be
better ways to purge the sstate cache files.
Thanks in advance
Michael.
The description looks good to me. By other ways you mean other usage
scenarios of sstate-cache-management.sh script or by means of something
else?
