// This script expects the current working directory to be `client`.

// Call it using:

// node updateSharedConfigVersions.mjs src/Try/SharedConfig.purs

//

// It keeps `SharedConfig.purs` in sync with the two sources of truth:

// - the PureScript compiler version, taken from the server's `stack.yaml`

// (the `purescript-X.Y.Z` extra-dep, i.e. the compiler that actually

// compiles user snippets);

// - the registry package set version, taken from `staging/spago.yaml`

// (the `registry:` field). With Spago v1 the package set is a registry

// version and no longer encodes a purs version, so the two are read

// independently. The footer URLs are derived from these values inside

// `SharedConfig.purs`, so only the version strings are written here.
