	/// <summary>
	/// The TarBuffer class implements the tar archive concept
	/// of a buffered input stream. This concept goes back to the
	/// days of blocked tape drives and special io devices. In the
	/// C# universe, the only real function that this class
	/// performs is to ensure that files have the correct "record"
	/// size, or other tars will complain.
	/// <p>
	/// You should never have a need to access this class directly.
	/// TarBuffers are created by Tar IO Streams.

/* A quote from GNU tar man file on blocking and records
   A `tar' archive file contains a series of blocks.  Each block
contains `BLOCKSIZE' bytes.  Although this format may be thought of as
being on magnetic tape, other media are often used.
