Dependencies
============
All tags within the dependencies tag define a set of requirements which have to be fulfilled in order to operate
properly. As soon as one of these requirements is not met the app cannot be installed.
php
---
Defines the minimum and the maximum version of php which is required to run this app.
database
--------
Each supported database has to be listed in here. Valid values are sqlite, mysql, pgsql, oci and mssql. In the future
it will be possible to specify versions here as well.
In case no database is specified it is assumed that all databases are supported.
command
-------
Defines a command line tool to be available. With the attribute 'os' the required operating system for this tool can be
specified. Valid values for the 'os' attribute are as returned by the php function `php_uname http://php.net/manual/en/function.php-uname.php`_.
lib
---
Defines a required php extension with required minimum and/or maximum version. The names for the libraries have to match the result as returned by the php function `get_loaded_extensions http://php.net/manual/en/function.get-loaded-extensions.php`_.
The explicit version of an extension is read from `phpversion http://php.net/manual/de/function.phpversion.php`_ - with some exception as to be read up in the code base `https://github.com/owncloud/core/blob/master/lib/private/app/platformrepository.php#L45`_
os
--
Defines the required target operating system the app can run on. Valid values are as returned by the php function `php_uname http://php.net/manual/en/function.php-uname.php`_.
owncloud
