+/* SUBSECTION
+	Tektronix Hex Format handling
+
+   DESCRIPTION
+
+	Tek Hex records can hold symbols and data, but not
+	relocations. Their main application is communication with
+	devices like PROM programmers and ICE equipment.
+
+	It seems that the sections are described as being really big,
+        the example I have says that the text section is 0..ffffffff.
+	BFD would barf with this, many apps would try to alloc 4GB to
+	read in the file.
+
+	Tex Hex may contain many sections, but the data which comes in
+	has no tag saying which section it belongs to, so we create
+	one section for each block of data, called "blknnnn" which we
+	stick all the data into.
+
+	TekHex may come out of 	order and there is no header, so an
+	initial scan is required  to discover the minimum and maximum
+	addresses used to create the vma and size of the sections we
+	create.
+	We read in the data into pages of CHUNK_MASK+1 size and read
+	them out from that whenever we need to.
+
+	Any number of sections may be created for output, we save them
+	up and output them when it's time to close the bfd.
+
+	A TekHex record looks like:
+  EXAMPLE
+	%<block length><type><checksum><stuff><cr>
+
+  DESCRIPTION
+	Where
+	o length
+	is the number of bytes in the record not including the % sign.
+	o type
+	is one of:
+	3) symbol record
+	6) data record
+	8) termination record
+
+  The data can come out of order, and may be discontigous. This is a
+  serial protocol, so big files are unlikely, so we keep a list of 8k chunks.  */
