45: The symbol table (name list) of each object in
46: .Ar file(s)
47: is displayed.
48: If a library (archive) is given,
1.4 aaron 49: .Nm
1.1 deraadt 50: displays a list for each
51: object archive member.
52: If
53: .Ar file

60: The options are as follows:

68: This involves removing extra underscores and making C++ function names readable.

70: Display the dynamic symbol table instead of the normal symbol table.
1.11 espie 71: .It Fl e
72: Output extended information, that is `w' for weak symbols, `f' for
73: function-like symbols, and `o' for object-like symbols.

! 87: has been specified; symbol name; symbol type;
! 88: symbol value and size (unless the symbol is undefined).
! 89: The radix of symbol values and sizes defaults to decimal, and may be changed

119: Each symbol name is preceded by its value (a blank field if the symbol
