I still do not like the give-me-the-full-path approach here ;) I'd propos=
e to=20
make the installer and package.xml work with so called "package groups". =
This=20
means that we define packages that belong to a certain group, like librar=
ies,=20
modules, or utils.

Accordingly, the filelist might look like this:

<filelist>
=09<file role=3D"php" group=3D"libraries" name=3D"my_package/1/class.php"=
/>
=09<file role=3D"php" group=3D"modules" name=3D"my_package/script.php"/>
</filelist>

As you see, the baseinstalldir attribute as well as the lib/ and modules/=
=20
directory are omitted. These are instead defined in the configuration fil=
e of=20
the installer itself:

installer/
=09conf/
=09=09config.xml

Here we might add:

<groups>
=09<group name=3D"libraries" baseinstalldir=3D"./lib/"/>
=09<group name=3D"modules" baseinstalldir=3D"./modules/"/>
</groups>

This is much more flexible, especially if we allow the installer to insta=
ll=20
different applications. For example, there can be applications called=20
"myIntranet" or "myWebsite", etc. Just imagine that each of these=20
applications uses ZZ/OSS Installer packages, but does not want to move th=
em=20
to the locations hardcoded in the package.xml file !

If modules should be physically located in components/ and libraries in=20
classes/ - then the initial filelist definition would not work, because t=
here=20
paths are hardcoded.

This furthermore means that package group definitions in=20
installer/config/config.xml must be application-specific. Maybe the solut=
ion=20
is to provide configuration files for each application, e.g.

installer/config/myIntranet.xml
installer/config/myWebsite.xml

But that's something for later. For now, we just have to add one package =
group=20
definition as shown above.
