+                    building out the data.

+                    and points to the cache locations to check for the shared

+                    You can specify a filesystem directory or a remote URL such 
+                    as HTTP or FTP.
+                    The locations you specify need to contain the shared state
+                    cache (sstate-cache) results from previous builds.
+                    The sstate-cache you point to can also be from builds on 
+                    other machines.

+                    you need to add 
+                    "PATH" at the end as shown in the examples below. 
+                    The build system substitues the correct path within the
