symbolic link confusion

In the past the test php apps that I've created have all been at the top level - meaning that the entrance page has always been at /home2/MYNAME/webapps/appname/index.php

No worries there.

Now I'm testing a micro-php framework that does the action-mapping for me in pure php code (trying to get away from writing all the glue code myself). This is only a test so far, but the documentation at Webfaction doesn't make it clear how this would be installed. On my test server at home I have to create a symbolic link in the apache conf that points the top level to (say) /var/www/testsite/webroot/ because /webroot/ is the directory that holds the index.php. At the same level as the webroot folder are other folders that hold parts of the application server, such that ../foldername/ is sprinkled throughout. Of course I can change all the mapping, but that is tedious.

I'd rather do something similar here at Webfaction that I do at my home server, meaning that the webroot directory will be the top directory (it will be /home2/MYNAME/webapps/appname/webroot/index.php where index.php is provided by the framework).

At Webfaction there are instructions on creating a symbolic link using the extra_info field, but that didn't seem to work on the first attempt. I received an error in the installation of the application. I know that index.php can be used at the top level as a type of forward, but that isn't spelled out anywhere in the Webfaction docs as supported.

Does someone know step-by-step how this can be done? Basically the webroot folder has its own .htaccess. I just need AFAICT to make sure that the "appname" folder has a symbolic link that says appname/webroot/ is actually the / folder for the app.

Thanks ahead of time
