------------------------+------------------------
 The nginx port's long description has not been modified since the port was
 added in 2007. Some of it is now anachronistic or in other need of
 updates:

 {{{
 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.
 }}}

 * the reference to running in production for over 2.5 years is quite
 surpassed by now, and probably that entire sentence is unnecessary
 * the mention of the type of license is unnecessary, given the portfile's
 `license` field
 * nginx is not still in beta; the first stable version was released in
 2011
