description         Lwan is a high-performance & scalable web server.

long_description    {*}${description} With its low disk and memory \
                    footprints, it's suitable to be used from embedded \
                    devices to robust servers. Both static and dynamic \
                    content can be served, as it can also be used as a \
                    library. Dynamic content can be generated by code written \
                    in either C or Lua.  Connections are handled individually \
                    by coroutines, which are transparently and efficiently \
                    juggled by a per-CPU cooperative scheduler, giving the \
                    illusion of blocking I/O to handlers. Lwan isn't just a \
                    simple static file server: it can be used as a library to \
                    build web services on top of it. In fact, the static file \
                    server isn't a special case: it just uses the same APIs \
                    that are available when Lwan is used as a library.
