//! This small crate is to let developers easily document items generated in
//! macros where the content of the documentation is dynamic.
//!
//! # Examples
//!
//! ```
//! #[macro_use]
//! extern crate docgen;
//!
//! doc!(
//! "Here is some documentation!"
//! ""
//! "Empty lines are represented by empty strings.";
//! pub fn foo() {}
//! );
//!
//! # fn main() {}
//! ```
//!
//! Commas can be used as delimitter between lines:
//!
//! ```
//! #[macro_use]
//! extern crate docgen;
//!
//! doc!(
//! "Here is some documentation!",
//! "",
//! "Empty lines are represented by empty strings.";
//! pub fn foo() {}
//! );
//! # fn main() {}
//! ```
//!
//! This is particularly useful when documenting items created by macros:
//!
//! ```
//! #[macro_use]
//! extern crate docgen;
//!
//! macro_rules! add_fn {
//! ($name:ident, $ty:ty) => {
//! doc!(
//! concat!("Add two [`", stringify!($ty), "`] values together.");
//! pub fn $name(a: $ty, b: $ty) -> $ty {
//! a + b
//! }
//! );
//! }
//! }
//!
//! add_fn!(add_u8, u8);
//! add_fn!(add_i8, i8);
//! # fn main() {}
//! ```
/// This macro is used to generate documentation upon an item.

/// #[inline]
