Not pertinent to this PR, but just wanted to note: looks like this pattern is becoming commonplace in a lot of our languages. Need to find a better solution. This commenting stuff feels wonky - if a user edits the file it isn't going to be clear to them that there's a hidden script that relies on the file's structure.

Binaries typically get placed in bin/ or so for most languages - what's the default that Crystal uses?

lib/ is where the dependencies are stored.
And server is the final artifact. (We are passing this name with the -o flag).

No other build artifacts would be there in the /app dir.
