/* SUBSECTION
	Verilog hex memory file handling

   DESCRIPTION

	Verilog hex memory files cannot hold anything but addresses
	and data, so that's all that we implement.

	The syntax of the text file is described in the IEEE standard
	for Verilog.  Briefly, the file contains two types of tokens:
	data and optional addresses.  The tokens are separated by
	whitespace and comments.  Comments may be single line or
	multiline, using syntax similar to C++.  Addresses are
	specified by a leading "at" character (@) and are always
	hexadecimal strings.  Data and addresses may contain
	underscore (_) characters.

	If no address is specified, the data is assumed to start at
	address 0.  Similarly, if data exists before the first
	specified address, then that data is assumed to start at
	address 0.


   EXAMPLE
	@1000
	01 ae 3f 45 12

   DESCRIPTION
	@1000 specifies the starting address for the memory data.
	The following characters describe the 5 bytes at 0x1000.  */
