[BRLTTY] Localization steps for Brltty?

[Hammer Attila]

Hi,

Longer time period I would like localizing Brltty messages for hungarian 
language.
I already see the Messages directory with fr.po, de.po, zh.po 
translation catalog files.
How can I  generate an empty hu.po translation catalog file to I have 
possibility begin this work? The fr.po file containing 715 translatable 
messages (703 full translated, and 12 untranslated messages).
Other translation related steps I have experiences fortunately, but for 
example the msginit -l hu command doesn't working, because not have an 
input pot file in the current directory. I not compiled yet with latest 
Brltty source from the git repository, I simple downloaded the source tree.
Future how can possible automaticaly updating the generated hungarian po 
file if the sources added new translatable messages? The intltool-update 
hu command future will be working? I ask this, because not have 
POTFILES.in file the Messages directory.

How can have possibility to translate Brltty user manual and help 
screens with a non english language?
