/*
* TODO LIST:
* - Better error checking. (focus on ntfs_dump_volume)
* - Comment things better.
* - More things at verbose mode.
* - Dump ACLs when security_id exists (NTFS 3+ only).
* - Clean ups.
* - Internationalization.
* - Add more Indexed Attr Types.
* - Make formatting look more like www.flatcap.org/ntfs/info
*
* Still not dumping certain attributes. Need to find the best
* way to output some of these attributes.
*
* Still need to do:
* $REPARSE_POINT/$SYMBOLIC_LINK
* $PROPERTY_SET
* $LOGGED_UTILITY_STREAM
