-/* Getopt for Microsoft C
-This code is a modification of the Free Software Foundation, Inc.
-Getopt library for parsing command line argument the purpose was
-to provide a Microsoft Visual C friendly derivative. This code
-provides functionality for both Unicode and Multibyte builds.
-Date: 02/03/2011 - Ludvik Jerabek - Initial Release
-Version: 1.0
-Comment: Supports getopt, getopt_long, and getopt_long_only
-and POSIXLY_CORRECT environment flag
-License: LGPL
-Revisions:
-02/03/2011 - Ludvik Jerabek - Initial Release
-02/20/2011 - Ludvik Jerabek - Fixed compiler warnings at Level 4
-07/05/2011 - Ludvik Jerabek - Added no_argument, required_argument, optional_argument defs
-08/03/2011 - Ludvik Jerabek - Fixed non-argument runtime bug which caused runtime exception
-08/09/2011 - Ludvik Jerabek - Added code to export functions for DLL and LIB
-02/15/2012 - Ludvik Jerabek - Fixed _GETOPT_THROW definition missing in implementation file
-08/01/2012 - Ludvik Jerabek - Created separate functions for char and wchar_t characters so single dll can do both unicode and ansi
-10/15/2012 - Ludvik Jerabek - Modified to match latest GNU features
-06/19/2015 - Ludvik Jerabek - Fixed maximum option limitation caused by option_a (255) and option_w (65535) structure val variable

+===
 A lightweight C++11 Distributed Hash Table implementation originally based on https://github.com/jech/dht by Juliusz Chroboczek.

 * Light and fast C++11 Kademlia DHT library.
 * Distributed shared key->value data-store
- * Clean and powerful distributed map API with storage of arbitrary binary values of up to 56 KB.
+ * Clean and powerfull distributed map API with storage of arbitrary binary values of up to 56 KB.
 * Optional public key cryptography layer providing data signature and encryption (using GnuTLS).
 * IPv4 and IPv6 support.
 * Python binding.

-
-    Let $N$ the DHT network, $n_0\in N$, a given node and the following probabilistic events:
-    \begin{itemize}
-        \item $A$: $\forall n \in N$ $n$ is unreachable by $n_0$, \emph{i.e.} $n_0$ lost connection
-            with $N$;
-        \item $B$: $S\subset N$, the nodes unreachable by $n_0$ with $k={|S|\over|N|}$;
-        \item $C$: $m \le |N|$ nodes are flagged as ``expired''.
-    \end{itemize}
-
-    We are interested in knowing $\P(A|C)$, \emph{i.e.} the probability of the event where $A$ occurs
-    prior to $C$. From the above, we immediately get
-    $$\left\{
-        \begin{array}{ll}
-            \P(C|A)       & = 1\\
-            \P(A) + \P(B) & = 1
-        \end{array}
-    \right.$$
-    Also, the event $A|C$ can be abstracted as the urn problem of draw without replacement. Then,
-        $$\P(C|B) = \prod_{i=0}^m \left[k|N| - i \over |N|\right] = \prod_{i=0}^m \left[k - { i \over |N| }\right]$$
-    Furthermore, using Bayes' theroem we have
-    \begin{align*}
-        \P(A|C) & = { \P(C|A)\P(A) \over \P(C|A)\P(A) + \P(C|B)\P(B)}\\
-                & = { \P(A) \over \P(A) + \P(C|B)\P(B) }\\
-                & = { \P(A) \over \P(A) + \P(C|B)\left[1 - \P(A)\right] }\\
-        \Rightarrow \forloop{counter}{0}{\value{counter} < 5}{\qquad}\quad  \P(A)  & =
-            \P(A|C)\left[\P(A) + \P(C|B)\left(1 - \P(A)\right) \right] \\
-        \Rightarrow \forloop{counter}{0}{\value{counter} < 2}{\qquad}\;\:\, \P(A)\left[{ 1 \over \P(A|C)} - 1\right] & =
-            \P(C|B)\left(1 - \P(A)\right) \\
-    \end{align*}
-    Finally,
-    \begin{equation}
-        \label{eq:final}
-        \left[{\P(A) \over 1 - \P(A)}\right]\left[{ 1 \over \P(A|C)} - 1\right] =
-            \prod_{i=0}^m \left[k - { i \over |N| }\right]
-    \end{equation}
-
-    From \eqref{eq:final}, we may set a plausible configuration $\{\P(A),\P(A|C),k,|N|\}$ letting us
-    produce results such as in table \ref{tbl:k_1_2}, \ref{tbl:k_2_3} and \ref{tbl:k_3_4}.

-.TH DHTNODE 1 2016-07-29
-
-.SH NAME
-.B dhtnode
- a simple OpenDHT command line node runner.
-
-.SH SYNOPSIS
-.B dhtnode [-h]
-
-.B dhtnode [-v [-l \fIlogfile\fP]] [-i] [-d] [-n \fInetwork_id\fP] [-p \fIlocal_port\fP] [-b \fIbootstrap_host\fP[:\fIport\fP]]
-
-.SH DESCRIPTION
-
-This program runs a simple OpenDHT node in an interactive way. If you rather
-want to run the node in daemon mode, option \fB'-d'\fP is provided. When running
-in the interactive shell, you benefit from the readline capabilities for writing
-your commands such as command history. Here are the available commands in the
-interactive shell:
-
-.EE
-    h, help    Print this help message.
-    q, quit    Quit the program.
-    log        Start/stop printing DHT logs.
-
-    Node information:
-    ll         Print basic information and stats about the current node.
-    ls         Print basic information about current searches.
-    ld         Print basic information about currenty stored values on this node.
-    lr         Print the full current routing table of this node
-
-    Operations on the DHT:
-    b ip:port             Ping potential node at given IP address/port.
-    g [key]               Get values at [key].
-    l [key]               Listen for value changes at [key].
-    p [key] [str]         Put string value at [key].
-    s [key] [str]         Put string value at [key], signed with our generated
-                          private key.
-    e [key] [dest] [str]  Put string value at [key], encrypted for [dest] with
-                          its public key (if found).
-
-.SH OPTIONS
-
-.TP
-\fB-h\fP
-Prints some help.
-
-.TP
-\fB-v\fP
-Enable the verbose mode (log to stdout by default)
-
-.TP
-\fB-l\fP \fIlog_file\fP
-Write log to file instead of stdout
-
-.TP
-\fB-i\fP
-Generate cryptographic identity for the node.
-
-.TP
-\fB-d\fP
-Run the program in daemon mode (will fork in the background).
-
-.TP
-\fB-n\fP \fInetwork_id\fP
-Specify the network id. This let you connect to distinct networks and prevents
-the merge of two different networks (available since OpenDHT v0.6.1).
-
-.TP
-\fB-p\fP \fIlocal_port\fP
-Use port \fIlocal_port\fP for the program to bind to.
-
-.TP
-\fB-b\fP \fIbootstrap_host\fP[:\fIport\fP]
-The program needs to be given a node to connect to the network. You use this
-option to provide the ip address of that node.

-      --performance         Launches performance benchmark test. Available args

-      --data-persistence    Launches data persistence benchmark test. Available

-
- pyroute2 >=0.3.14
- matplotlib
- GeoIP (used by `scanner.py` for drawing map of the world)
- ipaddress
- netifaces
- networkx
- numpy
-
-## Usage
-
-Before running the script, you have to build and install OpenDHT and its cython
-wrapper (`cython3` has to be installed) on the system so that it can be found by
-the benchmark script.
-
-    $ cd $OPENDHT_SRC_DIR
-    $ ./autogen.sh
-    $ ./configure
-    $ make && sudo make install
-
-Then, you can use the script like so:
-
-    $ cd $OPENDHT_SRC_DIR/python/tools/
-    $ python3 benchmark.py --performance -t gets -n 2048
