Welcome to sysroot cruft finding utility.
$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).
--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.
