Copper is an open source scripting language aimed at game development in D.
Inspiration is taken from Go, D and Lua for the syntax.
See some of the tests in the tests/ directory.
When building copper for release mode it's important to have the build flag --build-mode=allAtOnce or the compilation will freeze at llvm-d.
Copper is released under the Boost license, as seen in LICENSE.md
Copper uses code from LLVM, which is under a different license.
