The files in this distribution comprise the set required to make six
executable files.  Three of these executables are (make read):

	read_x_tape		Reads RTOG patient exchange data files in
				a generic form which excludes saving the
				files read.

	ident_x_tape		Reads an RTOG patient exchange data file
				set directory file, parses it and reports on
				the data contained in the file set.  The
				Individual data files (other than the 
				directory file) are not parsed, just checked 
				for existence.

	read_tape		Reads a magnetic tape written according to
				the RTOG format with given buffer size (2048
				bytes is the default) and writes the files
				to disk using file names of aapm0000, aapm0001,
				etc., based on their order on the tape.  
				Reading concludes when the maximum number of
				files have been read or a double file mark is
				encountered.

While these programs may be built from the accompanying "Makefile", they do
not provide a complete diagostic tool for evaluating RTOG formatted file sets.
In order to do a complete evaluation, the content (not evaluated by these
programs) must be evaluated separately from the syntax used (mostly evaluated
by these routines).  This requires that the modules in the source file
'save_gen_files.c' must be written.  This is a complex task and is best done by
someone with intimate knowledge of the target (host) RTP systems file formats
and interconnection.


The other three executables are (make write):

	write_genx_tape		Would generate RTOG exchange format files if
				the internal data structures were filled in by
				someone familiar with the underlying RTP system.

	write_tape		Will put RTOG format files onto a tape medium.
				Comparable to "read_tape".

	block_text_file		This program will take a text file and put it
				into RTOG exchange format including blocking.
