 ## Detailed Design
 
-Swiftly itself will be a SPM project consisting of several executable products, one per supported platform, and all of these will share the core module that handles argument parsing, printing help information, and dispatching commands. Each platform’s executable will be built to statically link the stdlib so that they can be run without having installed Swift first.

 If neither of these steps find the package, then we'll consider the dependency as not installed, and print a message that shows users how to install it using the system package manager (e.g. `apt` on Ubuntu).
