On the home page of http://www.phpdoc.org/, on http://manual.phpdoc.org/HTMLSmartyConverter/HandS/phpDocumentor/tutorial_phpDocumentor.quickstart.pkg.html, and on https://github.com/phpDocumentor/phpDocumentor2, instructions to install phpDocumentor are:
pear channel-discover pear.phpdoc.org
pear install phpdoc/phpDocumentor
When I do so, I see that it is deprecated:
[root@desktop ~]# pear channel-discover pear.phpdoc.org
Adding Channel "pear.phpdoc.org" succeeded
Discovery of channel "pear.phpdoc.org" succeeded
[root@desktop ~]# pear install PhpDocumentor
