How to capiltalize only the first leter of a string?

[luciano de souza <luchyanus@...>]

Hello all,
It seems to be so simpler, but in spite of this, I could not think a
simpler way to do.
I have the following string:

name = 'luciano'

The first leter should be capitalized , but only the first one. If I
use "string.upper(name)", all the string will be changed.
So, my question is, how to get "Luciano", as the changed string, in
other others, how to ccapitalize only one character?
Regards,
Luciano
