    Targeted for 0.5 Alpha 2
   
  Targeted for 0.5 Alpha 1      * ZConfig Integration
   
     * Finish tutorial chapter 2        - A 'config.ZConfig' module that provides "PEAK-aware" versions of ZConfig
           services (e.g. it will use 'peak.naming' to resolve URLs)
   
         - App startup tools based on ZConfig files.
   
         - Sample 'AdaptiveTask' classes that perform the same functions as those in
           the MetaDaemon package, with a ZConfig schema to run them in a daemon-like
           application.
   
       * Fix issue w/reading XMI 1.1 files where metamodel has nested packages
   
       * Generate UML 1.4 and 1.5 and CWM 1.0 and 1.1, and add them to the
         'setup.py' package lists.
   
   
   
    Targeted for 0.5 Beta 1
   
     * Updated reference docstrings for 'peak.api', 'peak.binding',      * Updated reference docstrings for 'peak.api', 'peak.binding',
       'peak.config', 'peak.exceptions', and 'peak.naming'.        'peak.config', 'peak.exceptions', and 'peak.naming'.
   
       * Finish tutorial chapter 2 (?)
   
       * Web publishing framework sufficient to deploy page-based or object-
         published apps
   
  Targeted for 0.5 Final Release (or sooner)      * Get XMI writing in place, w/transaction support
   
       * On-the-fly class combination (think "runtime module inheritance",
         without the modules) for DMs.

     * More S-E-F metadata: features, subclasses, svc.<->class, nested services

   peak.metamodels.uml  
   
     * Need to write an MMX or XMI -> Python generator, and hook it back up into  
       the UML package, since we're right now relying on a module generated  
       by code that depends on stuff which is going away.
