Using Console_CommandLine

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?

You need to setup your include path. PEAR packages rely on it being set correctly, so that their includes work properly:

set_include_path('.:/A_PATH/lib/php/');

You can also set that in your php.ini, which is how it's done most times.

A howto to setup your include path can be found in the PEAR 1 manual: http://pear.php.net/manual/en/installation.checking.php
