//
// 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.
//
