+"""Wrapper around actool to compile assets catalog.
+
+The script compile_xcassets.py is a wrapper around actool to compile
+assets catalog to Assets.car that turns warning into errors. It also
+fixes some quirks of actool to make it work from ninja (mostly that
+actool seems to require absolute path but gn generates command-line
+with relative paths).
+
+The wrapper filter out any message that is not a section header and
+not a warning or error message, and fails if filtered output is not
+empty. This should to treat all warnings as error until actool has
+an option to fail with non-zero error code when there are warnings.
