| Subprocess is a cross-platform package for spawning processes in Swift. | ||

| It's like [Foundation.Process](https://developer.apple.com/documentation/foundation/process), but written for Swift and build on top of structural concurrency. |

From your proposal and inspiration from foundation's other packages

| It's like [Foundation.Process](https://developer.apple.com/documentation/foundation/process), but written for Swift and build on top of structural concurrency. | |
| It improves the ergonomics of `Foundation.Process` and the experience of using Swift for scripting and other areas such as server-side development, with first-class integration with `async/await` and other language features. |

Tony actually suggested to remove this line altogether 😅

Previous, we would encounter missing symbol errors like:
"_subprocess_vm_size()", referenced from:
closure swiftlang#1 () -> Swift.Int in variable initialization expression of Subprocess.(_pageSize in _EDE99368FF43462E0C75AF3C9D4D8F2D) : Swift.Int in AsyncBufferSequence.swift.o
NOTE: found '__subprocess_vm_size' in process_shims.c.o, declaration possibly missing 'extern "C"'
We can reproduce this by running:
xcrun swift build -Xswiftc -cxx-interoperability-mode=default --build-tests
Adding `extern "C"` fixes these issues.

I will address the following issues separately (before we tag
0.0.1) once this PR lands since it's big enough as it is:
