This follows a simple convention:
- `main.rs` contains as little as possible and delegates both
data-types definitions and command executions to sub-modules.
- modules are named after their respective commands. For
sub-commands,
- Each command module can be in one of two forms:
- Either it is a leaf command, and it then contains an `Args`
struct that defines the command arguments; and a function
`exec` when outlines the execution logic.
- Or, it is a group command with multiple sub-commands. In which
case the module defines a `Cmd` struct encapsulating all
sub-commands; and also an `exec` function which simply
dispatches the logic to sub-functions.
---
This commit also removes the `dev` command which is currently
unused. The rationale being: if it's not there, it's not there.
