FUNCTIONS

    LoadFile

      my $structure = LoadFile('/path/to/yml'[, $force_reload]);

      Loads the structure from '/path/to/yml' into $structure, preferring
      the cached version if available, otherwise reading the file and
      caching the result for 593 seconds (about 10 minutes).

      If $force_reload is set to a true value, the file will be loaded from
      disk without regard to the current cache status.

    DumpFile

      DumpFile('/path/to/yml', $structure);

      Dump the structure from $structure into '/path/to/yml', filling the
      cache along the way.

    FlushCache

      FlushCache();

      Remove all currently cached YAML documents from the cache server.

    FreshenCache

      FreshenCache();

      Freshen currently cached files which may be out of date, either by
      deleting the cache (for now deleted files) or reloading from the disk
      (for changed ones)

      May optionally provide a list of files to check, otherwise all known
      cached files are checked.

      Returns a stats hash-ref.
