[Owncloud] App Requirements

[Florian Hülsmann]

Hey Tom,

actually I wrote a proposal about dependencies of apps (mainly apps 
depending on other apps) to this mailing list on 8th of april, hoping to 
start a constructive discussion about it...

I thought about something like this:

<info>
   <!-- app info -->
   <requires id="required_app">
     <!-- to define specific versions of required_app, optional -->
     <min>0.2</min> <!-- optional -->
     <max>0.5</max> <!-- optional -->
     <version>0.15</version> <!-- a specific version; optional -->
     <version>0.16</version> <!-- optional -->
   </requires>
   <requires id="another_app" />

   <conflicts id="evil_app">
     <max>0.3</max> <!-- same version properties as above -->
   </conflicts>
   <!-- ... -->
</info>

But we could make this even possible for PHP libraries etc.

Cheers

Florian
