## Disclaimer
This is a fork of the original library [lsalzman/enet](https://github.com/lsalzman/enet). While original repo offers a stable, time-tested wonderful library,
we are trying to change some things, things, which can't be reflected on the main repo, like:
* integrated ipv6 support
* added monotonic time
* applied project-wide code style change
* cleaned up project
* single-header style code
* NPM package distribution
* removed a lot of older methods
* and many other various changes
