Direction of this project

We haven't decided whether we should increase this library's contents or not because there are pros and cons. If you are interested in this topic, please join the discussion in The Announcement of Codeforces.

For now, we are not planning to add new features, and we use this repository only for

• collecting issues
• recording the changelogs
• versioning our releases

Contributing

We would appreciate it if you would report our mistakes like a typo, or, more importantly, bugs!

As mentioned above, we haven't decided which way to go. Therefore we close PRs and feature requests for now.
