//! Macros used on ouch.

/// Macro that prints \[INFO\] messages, wraps [`eprintln`].
///
/// There are essentially two different versions of the `info!()` macro:
/// - `info!(accessible, ...)` should only be used for short, important
///   information which is expected to be useful for e.g. blind users whose
///   text-to-speach systems read out every output line, which is why we
///   should reduce nonessential output to a minimum when running in
///   ACCESSIBLE mode
/// - `info!(inaccessible, ...)` can be used more carelessly / for less
///   important information. A seeing user can easily skim through more lines
///   of output, so e.g. reporting every single processed file can be helpful,
///   while it would generate long and hard to navigate text for blind people
///   who have to have each line of output read to them aloud, whithout to
///   ability to skip some lines deemed not important like a seeing person would.
