+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).
+
+ --whitelist=<whitelist-file>
+ Text file, each line is regular expression for paths we want to ignore in resulting diff.
+ You can use diff file from the script output, if it contains only expected exceptions.
+ '#' is used as regexp delimiter, so you don't need to prefix forward slashes in paths.
+ ^ and $ is automatically added, so provide only the middle part.
+ Lines starting with '#' are ignored as comments.
+ All paths are relative to "sysroots" directory.
+ Directories don't end with forward slash.
