- Welcome to utility to compare sstate checksums between different MACHINEs.

- 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
