Re: [Py2exe-users] problem using py2exe with turbogears (and eggs) to build an exe :(

[Oisin M. <oi...@en...>]

update:

I came across another utility called tg2exe. I know it doesn't use 
py2exe, however
I'm not having much luck with it either. I don't seem to be able to make 
any progress
using either tools :(

Has anyone ever had any luck make a standalone tg exe. I'll try post on
turbogears instead in a day or so maybe if no one responds.

Thanks,

Oisin
