It's preferable to use Zanata interface to translate documents.

If you want to translate documents through another tool, use always the .po files, ignore .pot files, they are used only for Zanata.

More information about pt_BR translation

The .pot files are used as template/source for all languages. In future we could generate them in the en_US.ISO8859-1 directory in FreeBSD Doc repository.

The Zanata Command line client (CLI) is the perfect way to connect to a Zanata server to push and pull content.

You can download zanata-cli here.

To config your zanata-cli:

cat ~/.config/zanata.ini
[servers]
translate_zanata_org.url=https://translate.zanata.org/
translate_zanata_org.username=YOUR_USERNAME
translate_zanata_org.key=YOUR_KEY

Main commands to push and pull translations:

zanata-cli push --push-type both --locales pt-BR

zanata-cli push --push-type trans --locales pt-BR
