Could we change this to mean the directory containing the LSOs instead of the
profile directory?

+   * systems (Windows), this will be encoded as UTF-8.
+   *
+   * @arg site String specifying which site to clear the data for. This will
+   * be null to clear data for all sites.
+   *
+   * @arg flags Currently always 0 in Chrome to clear all data. This may be
+   * extended in the future to clear only specific types of data.
+   *
+   * @arg max_age The maximum age in seconds to clear data for. This allows the
+   * plugin to implement "clear past hour" and "clear past data", etc.
+   *
+   * @return PP_TRUE on success, PP_FALSE on failure.
