-//! - **reveal** - Enables usage of the [`reveal`] function. On Linux this will pull in the
-//!   [`dbus`](https://docs.rs/dbus) crate. If the **dbus-vendored** feature is enabled (which it

-//!   some system dependencies will be required to build `dbus` and also to run any built binaries.
-//!   Refer to the [`dbus` docs](https://github.com/diwic/dbus-rs#requirements) for the specifics.
