I have installed Console_CommandLine using pyrus:
php pyrus.phar install pear/Console_CommandLine
the directory where Console_CommandLine was installed has the next structure:
(/A_PATH/lib/)
lib/
├── cache
├── data
├── docs
├── downloads
├── php
└── tests
I've tried the next:  (/A_PATH/demo.php)
<?php
    require_once 'lib/Console_CommandLine/php/Console/CommandLine.php';
    ...
 ?>
but I have the next error:
PHP Warning:  require_once(Console/CommandLine/Exception.php): failed to open stream: No such file or directory in /A_PATH/lib/Console_CommandLine/php/Console/CommandLine.php on line 32
PHP Fatal error:  require_once(): Failed opening required 'Console/CommandLine/Exception.php' (include_path='.:/usr/share/php:/usr/share/pear') in /A_PATH/lib/Console_CommandLine/php/Console/CommandLine.php on line 32
How can I use the CommandLine.php file for my personal project?
