Freedom Issue #3143
Whilst this package is already in the libre repo and has a lot of proprietary data removed, it turns out that even more proprietary data is lurking within.
The Adam Bolt 16×16 tiles have no license and as such are proprietary.
There may be proprietary headers for Windows.
I fear there may be even more proprietary files which have not been spotted yet.
