// 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 invokations so far:
// 1) `v init` -> create a new project in the current folder
// 2) `v new abc` -> create a new project in the new folder `abc`, by default a "hello world" project.
// 3) `v new abcd web` -> create a new project in the new folder `abcd`, using the vweb template.
// 4) `v new abcde hello_world` -> create a new project in the new folder `abcde`, using the hello_world template.

// Note: run `v cmd/tools/vcreate_test.v` after changes to this program, to avoid regressions.
