// Putting 3 times / : code comment --> documentation comment
// This feature displays the comment in markdown on the crates.io webpage

// reexporting the modules can be very useful when wanting to simplify the use of your crates for other devs:
// pub use self::utils::importantStuff
// makes importantStuff available as:
// use publishing_crates::importantStuff
// which is more intuitive for crate users.
