[luatex] invitation for Lua Workshop in Rio

[Luiz Henrique de Figueiredo]

Dear Hans Hagen,
We are planning a Lua Workshop in Rio to commemorate 30 years of Lua.
The event will be held at PUC-Rio on 17 October.
We would like to invite you to come and talk about your experience
with Lua. Unfortunately, we can't offer financial support for your
trip; we hope you can come anyway.
Please let us know.
--lhf, for the Lua team.
