%description
Crystal is a programming language with the following goals:
 + Have a syntax similar to Ruby (but compatibility with it is not a goal).
 + Be statically type-checked, but without having to specify the type of variables or method arguments.
 + Be able to call C code by writing bindings to it in Crystal.
 + Have compile-time evaluation and generation of code, to avoid boilerplate code.
 + Compile to efficient native code.
