single-file distributable web server
          redbean makes it possible to share web applications that run offline
          as an single-file [1]αcτµαlly pδrταblε εxεcµταblε zip archive which
          contains your assets. All you need to do is download the redbean.com
          program below, change the filename to .zip, add your content in a zip
          tool like Windows 10 or InfoZIP, and change the extension back to
          redbean can serve 1 million+ gzip encoded responses per second on a
          cheap personal computer. That performance is thanks to zip and gzip
          using the same compression format, which enables kernelspace copies.
          Another reason redbean goes fast is that it's a tiny static binary,
          which makes fork memory paging nearly free.
          redbean is also easy to modify to suit your own needs. The program
          itself is written as a single .c file.

          Assets can be listed by running the following command:
          unzip -vl redbean.com        # lists files   
          Assets can be added to the zip archive as follows:
          zip redbean.com index.html   # adds file   
          By default, anything you add to the archive gets compressed. Sometimes
          you don't want that to happen. A good example is video files. The web
          browser will want to send HTTP range requests to seek in the video, in
          which case redbean requires that the asset be uncompressed.
          zip -0 redbean.com video.mp4  # adds file without compression   
          Each connection uses a point in time snapshot of your ZIP file. If
          your ZIP is deleted then serving continues. If it's replaced then
          issuing SIGUSR1 (or SIGHUP if daemon) will reindex the zip for
          subsequent connections without interrupting active ones. If SIGINT or
          SIGTERM is issued then a graceful shutdown is started but if it's
          issued a second time, active connections are reset.
