 The `node-irc` library isn't well maintained and there are a number of issues which are impacting development of the [Matrix-IRC application service](http://github.com/matrix-org/matrix-appservice-irc). We made the decision to fork the project in order to improve reliability of the application service. A summary of modifications from `[email protected]` are below:
  - https://github.com/matrix-org/node-irc/pull/1 - Manifested as [BOTS-80](https://matrix.org/jira/browse/BOTS-80)
  - https://github.com/matrix-org/node-irc/pull/4 - Manifested as [BOTS-73] (https://matrix.org/jira/browse/BOTS-73)
- - Addition of `onNickConflict()` option which is called on `err_nicknameinuse`. This function should return the next nick to try. Defaults to suffixing monotonically increasing integers.
