## Extension macros for output to the rust _log_ crate

Most notably this includes a set of _-v_ suffix macros
(e.g. `debugv!`) that provide a superset of the `std::dbg!` feature.

This unenlightened wanderer (游侠) wrote a _log_ crate [PR] and
[RFC 317: _Inline Expression and Value Logging_][RFC 317], before publishing
the work as this standalone crate.

See the [rustdoc](https://docs.rs/tao-log) for usage details.

## Minimum supported rust version (MSRV)

1.31.0

The project will fail fast on any lower rustc (via a build.rs version
check) and is also CI tested on this version, included both 2015 and 2018 edition
external macro imports. A PR would be considered to backport the project to
earlier rust versions, possibly as far back as 1.16.0 (_log_'s current MSRV).
Or consider lobbying for the inclusion of this feature in _log_ itself.
