 GNU @code{nm} lists the symbols from object files @var{objfile}@dots{}.
+If no object files are listed as arguments, @code{nm} assumes
+@file{a.out}.
+
+For each symbol, @code{nm} shows:
+
+@itemize @bullet
+@item
+The symbol value, in the radix selected by options (see below), or
+hexadecimal by default.
+
+@item
+The symbol type.  At least the following types are used; others are, as
+well, depending on the object file format.  If lowercase, the symbol is
+local; if uppercase, the symbol is global (external).
+
+@c Some more detail on exactly what these symbol types are used for
+@c would be nice.
