Papo is team collaboration platform composed of a suite of free and open source
software made for communities and companies.  It features chat messaging, file
sharing and virtual workspaces for working online together.

Papo improves on existing solutions by:

1. offering glossy UI for the needs of modern users;
2. being built on existing stabilished standards, enabling existing workflows
   and infrastruture to interoperate, instead of creating yet another ad-hoc
   messaging API;
3. being 100% free-software, down to the server configuration files and its
   acompanying guides on how to use, customize or self-host, eliminating all
   forms of lock-in;
4. offering a hosted option at `https://papo.im` for those who whish to pay for
   a managed service that is as transparent as possible.

The software is made as close to zero-config as possible, both to make itself
simpler but also to make it easier for those who wish to self-host.

Underneath all of this, is just plain old IRC.  Not "a compatibility layer to
IRC", just IRC.  Most of "modern" functionalities are available via the "modern"
option which implements IRCv3 plus a couple of extensions, and there's also a
"classic" ircd option with traditional RFC 1459 capabilities which serves as a
replacement to other traditional ircd implementations.
