"""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).
