"""#
let _asciiString = #"""
Swift is a high-performance system programming language. It has a clean
and modern syntax, offers seamless access to existing C and Objective-C code
and frameworks, and is memory safe by default.
Although inspired by Objective-C and many other languages, Swift is not itself
a C-derived language. As a complete and independent language, Swift packages
core features like flow control, data structures, and functions, with
high-level constructs like objects, protocols, closures, and generics. Swift
embraces modules, eliminating the need for headers and the code duplication
they entail.
Swift toolchains are created using the script
[build-toolchain](https://github.com/apple/swift/blob/main/utils/build-toolchain).
This script is used by swift.org's CI to produce snapshots and can allow for
one to locally reproduce such builds for development or distribution purposes.
A typical invocation looks like the following:
```
$ ./swift/utils/build-toolchain $BUNDLE_PREFIX
```
where ``$BUNDLE_PREFIX`` is a string that will be prepended to the build date
to give the bundle identifier of the toolchain's ``Info.plist``. For instance,
if ``$BUNDLE_PREFIX`` was ``com.example``, the toolchain produced will have
the bundle identifier ``com.example.YYYYMMDD``. It will be created in the
directory you run the script with a filename of the form:
``swift-LOCAL-YYYY-MM-DD-a-osx.tar.gz``.
