/**
 * @file  multiotp.cli.header.php
 * @brief Command line implementation of the multiOTP PHP class.
 *
 * multiOTP PHP CLI header - Strong two-factor authentication PHP class
 * https://www.multiotp.net
 *
 * Visit http://forum.multiotp.net/ for additional support.
 *
 * Donation are always welcome! Please check https://www.multiOTP.net
 * and you will find the magic button ;-)
 *
 * If the name of this file is multiotp.php, it means that it is already
 * the result of the merge of the two files multiotp.cli.header.php and
 * multiotp.class.php
 *
 * The MultiOTP PHP CLI header is simply merged with the MultiOTP PHP
 * class in order to provide an authentication command line script.
 *
 * This script can be used as an external authentication provider with at
 * least the following RADIUS servers:
 *  - TekRADIUS LT, a free Radius server for Windows with SQLite backend
 *    (http:/www.tekradius.com)
 *  - TekRADIUS, a free Radius server for Windows with MS-SQL backend
 *    (http:/www.tekradius.com)
 *  - FreeRADIUS, a free Radius server implementation for Linux
 *    and *nix environments (http://freeradius.org)
 *  - WinRADIUS, the FreeRADIUS implementation ported for Windows
 *    (http://winradius.eu/)
 *
 * For Windows, you can also use the multiotp.exe file provided, which is
 * an embedded PHP interpreter together with the result of the merge.
 *
 * PHP 5.4.0 or higher is supported.

 * Command line usage
 *
 *   Type multiotp -help to have the full description of the options,
 *    and have a look at the readme.txt file for enhanced explanations
 *
 *
 * Return codes: see multiOTP class
 *
 *
 * Radius integration examples
 *
 *   Example 1 (FreeRADIUS 2.x under Linux or Windows, new fashion)
 *
 *     Have a look in the readme file, everything is explained.
 *
 *
 *   Example 2 (FreeRADIUS under Linux or Windows, old fashion)
 *
 *     Define a DEFAULT entry in the /etc/freeradius/users file like this:
 *     DEFAULT Auth-Type = Accept
 *     Exec-Program-Wait = "/usr/local/bin/multiotp.php %{User-Name} %{User-Password}",
 *     Fall-Through = Yes,
 *     Reply-Message = "Hello, %{User-Name}"
 *
 *
 *   Example 3 (TekRADIUS or TekRADIUS LT under Windows)
 *
 *     TekRADIUS supports a Default Username to be used when a matching user
 *     profile cannot be found for an incoming RADIUS authentication request.
 *     So a quick and easy way is to create in the TekRADIUS Manager a User
 *     named 'Default' that belongs to the existing 'Default' Group.
 *     Then add to this Default user the following attribute :
 *     Check  External-Executable  C:\multitop\multiotp.exe %ietf|1% %ietf|2%
 *
 *
 * External files created
 *
 *   Users database files in the subfolder called users
 *   Tokens database files in the subfolder called tokens
 *
 *
 * External file needed
 *
 *   Users database files in the subfolder called users
 *   Tokens database files in the subfolder called tokens
 *
 *
 * Special issues
 *
 *   If you need specific developements concerning strong authentication,
 *   do not hesistate to contact us per email at info@multiotp.net.
