A demo piping a string through a plug-in written in each PDK: Each plug-in exports a function that takes a string and appends "Hello from $lang!" to it. It effectively does this:

print(csharp(fsharp(rust(c(js(go("Hello from Python!")))))))

Building (note: this won't setup all the dependencies for you):

make build

Running:

make run
