eGroupWare/phpGroupWare Compatibility Layer
(Note: the tarball got lost.)
The attached tarball can be used as a stub Horde application with HEAD versions of Horde (3.2 and later) to map xml-rpc calls that expect phpgw's API into Horde.
Setup
First add the following code to horde/config/registry.php:
<pre><code class="language-php">
$this->applications['phpgw'] = array(
    'fileroot' => dirname(__FILE__) . '/../phpgw',
    'webroot' => $this->applications['horde']['webroot'] . '/phpgw',
    'name' => _("phpGW Adaptor"),
    'status' => 'notoolbar',
    'provides' => 'phpgw',
);
</code></pre>
Then extract the attached package into the horde directory.
Now you may read your calendar with any eGroupWare/phpGroupWare compatible calendar application.<br />
Use http[s](s)://<host>/path/to/horde/rpc.php?phpgw as server side url.
How it works
Each xmlrpc request using a phpgw unique name is implemented by this module mapping it into horde registry commands.<br />
A lot of data is stored in the horde datatree, to map kronolith calendar ids into numeric phpgw one's.
