Note: this was posted in this Stack Overflow
question, where I was advised to cross post here.

I am writing a package to facilitate importing Brazilian socio-economic
microdata sets (Census, PNAD, etc). I foresee two distinct groups of users
of the package:


   Users in Brazil, who may feel more at ease with the documentation in
   Portuguese. The probably can understand English to some extent, but a
   foreign language would probably make the package feel less "ergonomic".

   The broader international users community, from whom English
   documentation may be a necessary condition.

Is it possible to write a package in a way that the documentation is
"bilingual" (English and Portuguese), and that the language shown to the
user will depend on their country/language settings?


Is that doable within the roxygen2 documentation framework?

I realise there is a tradeoff of making the package more user-friendly by
making it bilingual vs. the increased complexity and difficulty to
maintain. General comments on this tradeoff from previous expirience are
also welcome.
