1//! `run-make-support` is a support library for run-make tests. It provides command wrappers and
2//! convenience utility functions to help test writers reduce duplication. The support library
3//! notably is built via cargo: this means that if your test wants some non-trivial utility, such
4//! as `object` or `wasmparser`, they can be re-exported and be made available through this library.
