runtime-cli 0.1.0

//! `runtime api '<query>'` — escape hatch for arbitrary GraphQL.
//!
//! Accepts an optional list of `--var key=value` pairs that compose
//! the `variables` object. Values are parsed as JSON first; on parse
//! failure they fall back to strings so `--var slug=alice/r1` does the
//! intuitive thing.
