//! A builder for Windows application manifest XML files.
//!
//! This module allows the construction of application manifests from code with the
//! [`ManifestBuilder`], for use from a Cargo build script. Once configured, the builder
//! should be passed to [`embed_manifest()`][crate::embed_manifest] to generate the
//! correct instructions for Cargo. For any other use, the builder will output the XML
//! when formatted for [`Display`], or with [`to_string()`][ToString]. For more
//! information about the different elements of an application manifest, see
//! [Application Manifests][1] in the Microsoft Windows App Development documentation.
//!
//! [1]: https://docs.microsoft.com/en-us/windows/win32/sbscs/application-manifests
//!
//! To generate the manifest XML separately, the XML can be output with `write!` or
//! copied to a string with [`to_string()`][ToString]. To produce the manifest XML with
//! extra whitespace for formatting, format it with the ‘alternate’ flag:
//!
//! ```
//! # use embed_manifest::new_manifest;
//! let builder = new_manifest("Company.OrgUnit.Program");
//! assert_eq!(format!("{:#}", builder), r#"<?xml version="1.0" encoding="UTF-8" standa lone="yes"?>
//! <assembly xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3" manifestVersion="1.0">
