# A guided tour of Ruby (mruby) running on calog.
# Demonstrates: a Range, reduce with a block, select with a symbol-to-proc, a Hash, then the
# jsonStringify/jsonParse and cryptoHashSha256 natives. Ruby's puts works; real file/socket IO
# is provided by calog's fs*/net* natives (not Ruby's stdlib) -- so scripts stay uniform.
