This current directory provides custom completions. They can be used by importing their exported commands via:

use path/to/<command>/<command>-completions.nu *
# or
source path/to/<command>/<command>-completions.nu
# without the `*` at the end

With path/to/<command> being either the relative path of the file to your current working directory or its absolute path.

Bear in mind that if you import the use <path> *, it is important that you don't name a function with the same name of the file

# file: rustup.nu 

export extern rustup [
    ...args
]

use ./rustup.nu * won't work here
