- [ ] Add a subcommand to dump the embedded templates so they can be
modified.
- [ ] Take binary files into account.
- [ ] Limit the output for large diffs.
- [ ] Allow to anchor lines.
- [ ] Check if the templates exist on a location and use them if
so. Allow to change that location through CLI flags or env vars.
- [ ] Optimize repository generation through a cache.
- [ ] Add a flag to regenerate in case a `push -f` comes in.
- [ ] Optimize output generation through the use of smaller templates
instead of having all the structs in memory when executing one
template (for large repos).
