+
+A command-line options parser with configurable expects and help auto generation.
+
+There is two kind of arguments :
+ - options (short/long tag) : _-h_ or _--version_
+ - values : my/path/to/a/file 
+
+### Description
+At first, create a new CommandLine with program name and description. Add options and values by using respectively _addOption_ and _addValue_.
+Default options for help (-h / --help) and version (--version) can be add with _addDefaultArguments_ and use _treatDefaultArguments_ for launching associated treatments.
+
+Treat script arguments with _parse_ : return an object of variables.
+
+### Example 
+```php
+<?php
+
+use CommandLine\CommandLine;
+use CommandLine\Argument\Option\Flag;
+use CommandLine\Argument\Parser\StringParser;
+use CommandLine\Argument\Value\Value;
+
+$cmdline = new CommandLine('Checker', 'File checker', 'php checker.php');
+$cmdline->addDefaultArguments();
+
+$cmdline->addOption(new Flag('enhanced', false, 'Deep check ?'));
+
+$cmdline->addValue(new Value('path', 'File path', new StringParser()));
+
+var_dump($args = $cmdline->parse());
+$cmdline->treatDefaultArguments($args);
+```
+
+Would display something like that : 
+
+    class stdClass#13 (1) {
+      public $enhanced => bool(false)
+      public $path     => string("my/path/to/a/file")
+    }
+
+

+
+    Checker
+    File checker
+    
+    php checker.php [OPTIONS] path
