+	<<typedef bfd>>
+
+	A BFD has type <<bfd>>; objects of this type are the
+	cornerstone of any application using BFD. Using BFD
+	consists of making references though the BFD and to data in the BFD.
+
+	Here is the structure that defines the type <<bfd>>.  It
+	contains the major data about the file and pointers
+	to the rest of the data.

+SYNOPSIS
+	long bfd_get_size(bfd *abfd);
+
+DESCRIPTION
+	Return the file size (as read from file system) for the file
+	associated with BFD @var{abfd}.
+
+	The initial motivation for, and use of, this routine is not
+	so we can get the exact size of the object the BFD applies to, since
+	that might not be generally possible (archive members for example).
+	It would be ideal if someone could eventually modify
+	it so that such results were guaranteed.
+
+	Instead, we want to ask questions like "is this NNN byte sized
+	object I'm about to try read from file offset YYY reasonable?"
+	As as example of where we might do this, some object formats
+	use string tables for which the first <<sizeof(long)>> bytes of the
+	table contain the size of the table itself, including the size bytes.
+	If an application tries to read what it thinks is one of these
+	string tables, without some way to validate the size, and for
+	some reason the size is wrong (byte swapping error, wrong location
+	for the string table, etc.), the only clue is likely to be a read
+	error when it tries to read the table, or a "virtual memory
+	exhausted" error when it tries to allocate 15 bazillon bytes
+	of space for the 15 bazillon byte table it is about to read.
+	This function at least allows us to answer the quesion, "is the
+	size reasonable?".
