# Scope
Oper is a basic history tool for git repositories managed by google's [git-repo tool](https://source.android.com/setup/develop/repo).
It can show the history of the last _n_ days across all managed git repositories.
Oper is inspired by [tig](https://jonas.github.io/tig/), but is far for more basic. Don't expect any commands or additional views.
# Installation
Oper is written in rust. You need the rust toolchain installed to be able to use it:
