   * The Unix 'faucet' program runs as a daemon in the background, awaiting
   * requests to the verify port.  When a connection occurs, this PHP script
   * is invoked.
   *
   * The protocol is simple:
   *   1) Read a line; this is the file name.
   *   2) Read file content, save it as the given name.
   *   3) Close the file.
   *
   * Run using:
   *   faucet 4242 --daemon --out --in php snapshot.php
