+Welcome to sysroot cruft finding utility.

+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.
