-// A tool to dump HTML5 filesystem from CUI.
-//
-// Usage:
-//
-// ./out/Release/dump_file_system [options] <filesystem dir> [origin]...
-//
-// If no origin is specified, this dumps all origins in the profile dir.
-//
-// Available options:
-//
-// -t : dumps temporary files instead of persistent.
-// -s : dumps syncable files instead of persistent.
-// -l : more information will be displayed.
-//
-// The format of -l option is:
-//
-// === ORIGIN origin_name origin_dir ===
-// file_name file_id file_size file_content_path
-// ...
-//
-// where file_name has a trailing slash, file_size is the number of
-// children, and file_content_path is empty if the file is a directory.
-//
