-  // Perform a crypto operation using the openssl(1) program. Throw
-  // process_error and io_error (both derive from system_error) in case of
-  // errors.
-  //
-  // The I (in) and O (out) can be of the following types/values:
-  //
-  // nullfd          Signal that no input/output is expected.
-  //
-  // path            Read input/write output from/to a file. If the special "-"
-  //                 value is used, then instead input is connected to the
-  //                 openssl::out ofdstream member and output -- to the
-  //                 openssl::in ifdstream member. Note that the argument type
-  //                 should be path, not string (i.e., pass path("-")). Also
-  //                 note that the streams are opened in the binary mode. To
-  //                 change that, use fdstream_mode::text instead (see below).
-  //
-  // fdstream_mode   Only text and binary values are meaningful. Same as
-  //                 path("-"), but also specifies the translation mode.
-  //
-  // other           Forwarded as is to process_start(). Normally either int or
-  //                 auto_fd.
-  //
-  // For example:
-  //
-  //   openssl os (path ("key.pub.pem"), // Read key from file,
-  //               path ("-"),           // Write result to openssl::in.
-  //               2,
-  //               "openssl", "pkey",
-  //               "-pubin", "-outform", "DER");
-  //
-  // Typical usage:
-  //
-  // try
-  // {
-  //   openssl os (nullfd,           // No input expected.
-  //               path ("-"),       // Output to openssl::in.
-  //               2,                // Diagnostics to stderr.
-  //               path ("openssl"), // Program path.
-  //               "rand",           // Command.
-  //               64);              // Command options.
-  //
-  //   vector<char> r (os.in.read_binary ());
-  //   os.in.close ();
-  //
-  //   if (!os.wait ())
-  //     ... // openssl returned non-zero status.
-  // }
-  // catch (const system_error& e)
-  // {
-  //   cerr << "openssl error: " << e << endl;
-  // }
-  //
-  // Notes:
-  //
-  // 1. If opened, in stream is in the skip mode (see fdstream_mode).
-  //
-  // 2. If opened, in/out must be explicitly closed before calling wait().
-  //
-  // 3. Normally the order of options is not important (unless they override
-  //    each other). However, openssl 1.0.1 seems to have bugs in that
-  //    department (that were apparently fixed in 1.0.2). To work around these
-  //    bugs pass user-supplied options first.
