Usage

• Add astroz as a dependency in your build.zig.zon.

zig fetch --save https://github.com/ATTron/astroz/archive/<git_tag_or_commit_hash>.tar.gz

• Use astroz as a module in your build.zig.

const astroz_dep = b.dependency("astroz", .{
    .target = target,
    .optimize = optimize,
});
const astroz_mod = astroz_dep.module("astroz");
exe.root_module.addImport("astroz", astroz_mod);
