const EXPECTED: &str = "\
cxxbridge 0.3.7
David Tolnay <dtolnay@gmail.com>
https://github.com/dtolnay/cxx
USAGE:
cxxbridge <input>.rs Emit .cc file for bridge to stdout
cxxbridge <input>.rs --header Emit .h file for bridge to stdout
cxxbridge --header Emit rust/cxx.h header to stdout
ARGS:
<input>
Input Rust source file containing #[cxx::bridge].
OPTIONS:
--cxx-impl-annotations <annotation>
Optional annotation for implementations of C++ function wrappers
that may be exposed to Rust. You may for example need to provide
__declspec(dllexport) or __attribute__((visibility(\"default\")))
if Rust code from one shared object or executable depends on
these C++ functions in another.
\x20
-h, --help
Print help information.
--header
Emit header with declarations only.
-i, --include <include>...
Any additional headers to #include. The cxxbridge tool does not
parse or even require the given paths to exist; they simply go
into the generated C++ code as #include lines.
\x20
-V, --version
Print version information.

let mut app = super::app();
let mut out = Vec::new();
app.write_long_help(&mut out).unwrap();
let help = String::from_utf8(out).unwrap();
