"""# Git-based Time Tracker.
Quick and dirty time tracker on git histories.
Uses the simple heuristics that each commit takes precisely one hour of work.
It will automatically trim commits below one hour if another commit occurred
less than an hour ago.
Usage:
```
python -m git_time_tracker REPO1 REPO2...
```
# Obligatory
This tool reports:
```
project Jmaa/git-time-tracker.git 3h 33m (2024)
```
And the ([Hamster](https://github.com/projecthamster/hamster)) manual time tracker reports:
