# Used to compare sstate checksums between MACHINES.
# Execute script and compare generated list.M files.
# Using bash to have PIPESTATUS variable.
# It's also usefull to keep older sstate checksums
# to be able to find out why something is rebuilding
# after updating metadata
# $ diff \

Welcome to utility to compare sstate checksums between different MACHINEs.
$0 <OPTION>
Options:
-h, --help
Display this help and exit.
--tmpdir=<tmpdir>
Specify tmpdir, will use the environment variable TMPDIR if it is not specified.
Something like /OE/oe-core/tmp-eglibc (no / at the end).
--machines=<machines>
List of MACHINEs separated by space, will use the environment variable MACHINES if it is not specified.
Default value is "qemuarm qemux86 qemux86-64".
--targets=<targets>
List of targets separated by space, will use the environment variable TARGETS if it is not specified.
Default value is "core-image-base".
--analyze
Show the differences between MACHINEs. It assumes:
* First 2 MACHINEs in --machines parameter have the same TUNE_PKGARCH
* Third optional MACHINE has different TUNE_PKGARCH - only native and allarch recipes are compared).
* Next MACHINEs are ignored
