One future enhancement is to (optionally) display debugger symbols.
If anyone has any information about the layout of the C$$DEBUG
area, I can get to work.
Lots of fun!

Arthur NM - Usage Notes
=======================
Copyright 1989 Colin R. Smale
NM is a tool to examine the symbol table of object files and object
libraries. The names and attributes of all symbols are displayed.
Usage:
nm [-a] [-n] file ...
Options:
-a uses alphanumeric sort (default)
-n symbols are sorted numerically by value
Options can be interspersed with filenames; they take effect
as from that point in the list of files.
If a file is a library created by LibFile and ObjLib, the information
is displayed for each module contained in the library.
Output:
One symbol is displayed on each line. The fields are:
Symbol value - normally the address relative to an area
for external references, this field is blank
Flags - the letters have the following meanings:
l local symbol
e external reference
d global definition
w external reference is weak
s global definition is strong
a symbol is absolute
@ linker will use case-insensitive matching
c common block
Symbol name
Area name - displayed between parentheses if symbol is relative
For more information, refer to the Acorn documentation on AOF and ALF
available from the SID database.
Errors will occur if:
- the file is not a chunk file
- the file does not contain AOF object
Bugs:
As usual, none known. The error checking could do with improvement.
If you find a problem or if you have a suggestion for improvement,
please contact the author:
