Hello, our project at launchpad have recently past the stage of manual
import of the template stage and we are able to start translation of
the help system on Launchpad.

Here is the link to the template:
https://translations.launchpad.net/gretl/trunk/+pots/gretl-help

I'm currently not on my linux laptop so I will try to generate
.po-files for pt_BR some time later as it was requested. We'll look
what it will be.
