+Helpers to extract symbols from Unix libs and auto-generate
+Windows definition files from them. Depends on nm(1). Tested
+on Linux and Solaris only (-p option to nm is for Solaris only).
+
+By Marc-Andre Lemburg, Aug 1998.
+
+Additional notes: the output of nm is supposed to look like this:
+
+acceler.o:
+000001fd T PyGrammar_AddAccelerators
+         U PyGrammar_FindDFA
+00000237 T PyGrammar_RemoveAccelerators
+         U _IO_stderr_
+         U exit
+         U fprintf
+         U free
+         U malloc
+         U printf
+
+grammar1.o:
+00000000 T PyGrammar_FindDFA
+00000034 T PyGrammar_LabelRepr
+         U _PyParser_TokenNames
+         U abort
+         U printf
+         U sprintf
+
+...
+
+Even if this isn't the default output of your nm, there is generally an
+option to produce this format (since it is the original v7 Unix format).
