// Note: this program follows a similar convention to Rust: `init` makes the
// structure of the program in the _current_ directory, while `new`
// makes the program structure in a _sub_ directory. Besides that, the
// functionality is essentially the same.
// Note: here are the currently supported invocations so far:
// - `v init` -> initialize a new project in the current folder
// - `v new` -> create a new project in the directory specified during setup, using the "bin" template by default.
// - `v new my_bin_project bin` -> create a new project directory `my_bin_project`, using the bin template.
// - `v new my_lib_project lib` -> create a new project directory `my_lib_project`, using the lib template.
// - `v new my_web_project web` -> create a new project directory `my_web_project`, using the vweb template.
