Example

Why don't you dry up src/foo/version.cr and shard.yml ?

1. Delete src/foo/version.cr
2. Use Shard.version in anywhere you want.

Otherwise, use it in src/foo/version.cr .

module Foo
  VERSION = Shard.version
end

license = Shard.license
year    = Shard.time.to_s("%Y")
author  = Shard.authors.first.to_s
