description         High-performance HTTP(S) server, HTTP(S) reverse proxy and IMAP/POP3 proxy server
long_description    \
    Nginx ("engine x") is a high-performance HTTP(S) server and reverse proxy, \
    as well as an IMAP/POP3 proxy server. Nginx was written by Igor Sysoev for \
    Rambler.ru, Russia's second-most visited website, where it has been running \
    in production for over two and a half years. Igor has released the source \
    code under a BSD-like license. Although still in beta, Nginx is known for \
    its stability, rich feature set, simple configuration, and low resource \
    consumption.
