* Spice up the project README, fill out more docs This is an attempt to spruce up wasmtime's README.md file as well as fill out more of the missing documentation in the `docs/` folder. There's still a long way to go but I hoped here to mostly move around existing information and add new information. As always happy to have feedback! * Tweak CLI wording * Remove no-longer relevant clause * Update sandboxing docs * Handle comments

# C/C++

All the parts needed to support wasm are included in upstream clang, lld, and
|
|
compiler-rt, as of the LLVM 8.0 release. However, to use it, you'll need
|
|
to build WebAssembly-targeted versions of the library parts, and it can
|
|
be tricky to get all the CMake invocations lined up properly.
|
|
|
|
To make things easier, we provide
|
|
[prebuilt packages](https://github.com/CraneStation/wasi-sdk/releases)
|
|
that provide builds of Clang and sysroot libraries.
|
|
|
|
WASI doesn't yet support `setjmp`/`longjmp` or C++ exceptions, as it is
|
|
waiting for [unwinding support in WebAssembly].
