## trepplein: a Lean type-checker

Lean is an interactive theorem prover based on dependent type theory.  For

additional trust, Lean can [export the generated proofs][1] so that they can be

independently verified.  Trepplein is a tool that can check these exported proofs.

[1]: https://github.com/leanprover/lean/blob/master/doc/export_format.md

Trepplein is written in Scala, and requires [SBT](http://www.scala-sbt.org/) to

build.

```

sbt stage

./target/universal/stage/bin/trepplein .../export.out

```
