Governments developing free software
This page is a collection of governments that develop software and publish it as free software. (For a list of examples of use of free software, see FSFE's wiki page: FS in public administration)

It's difficult to define "government", since one could include "government bodies" or third-parties contracted to do some work, but the purpose of this page is collect examples where the development and publishing of the software is close enough to the government to imply some form of endorsement or at least satisfaction. So it's a fairly narrow definition of "government".
