-%description
-Libevent based HTTP API.Libevent's http interface was created as a JIT server, never meant
-to be a full-fledged HTTP service. This library attempts to improve on that with the following
-features: + design as a fully functional HTTP server + HTTP parser able to process data with a
-low memory footprint + use of regular expressions for routing + out-of-the box HTTPS server
-This package contains the runtime library.
