nm2def.py
#! /usr/bin/env python
"""nm2def.py
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).
