Dropbox-php
===========
This PHP library allows you to easily integrate dropbox with PHP.
The following PHP extension is required:
* json
The library makes use of OAuth. At the moment you can use either of these libraries:
[PHP OAuth extension](http://pecl.php.net/package/oauth)
[PEAR's HTTP_OAUTH package](http://pear.php.net/package/http_oauth)
The extension is recommended, but if you can't install php extensions you should go for the pear package.
Installing
----------
pear channel-discover pear.dropbox-php.com
pear install dropbox-php/Dropbox-alpha
