GPL-friendly fonts: Bitstream-Vera
It's not the purpose of Novelang to come with its own set of fonts and this could turn licensing to a mess. But testing require a set of valid fonts and since the project is public, I'm reluctant to put a font I've no rights to distribute under the version control system. Lucky me I discovered the Bitstream Vera Fonts with a license which is GPL-compatible (they're used under a Linux-related project). Those fonts are designed for screen display rather than printing but they behave quite well and provide a very complete family which is perfect for various tests. If you're interested you can download them from here. Nice work, guys!
