#! /usr/bin/env python"""nm2def.py Helpers to extract symbols from Unix libs and auto-generateWindows definition files from them. Depends on nm(1). Testedon 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_FindDFA00000237 T PyGrammar_RemoveAccelerators         U _IO_stderr_         U exit         U fprintf         U free         U malloc         U printf grammar1.o:00000000 T PyGrammar_FindDFA00000034 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 anoption to produce this format (since it is the original v7 Unix format).
