logging:
   - logging from type emulator without clobbering stdout
      maybe implement logging server as described here [1]
   [1] http://docs.python.org/py3k/howto/logging-cookbook.html#configuration-server-example

   - use different logger to limit output to current area of interest,
      e.g.
         explorer.$target_host: explorer related messages for the run for $target_host
         manifest.$target_host: manifest related messages for the run for $target_host
         ...
      then one could filter e.g. on explorer.*

   - more granular debug output,

config_install:
   - move code for running global and type explorer run to cdist.core.explorer

tests:
   - aufraeumen
   - test suite


tests:

   __init__():
      - sets up env: __target_host

   run_initial_manifest():
      - parameter is actually used (from __init__)
      - ensure changing the manifest actually runs a different manifest
      -> give ConfigInstall Constructor different manifest
         -> different manifest is executed.
      - test all submitted (from core to type manifest) variables:
         - ENVIRONMENT
         - they are set
         - they contain the correct values

   run_type_manifest():
      - test all submitted (from core to type manifest) variables:
         - ENVIRONMENT
         - they are set
         - they contain the correct values
      - same tests as for test_initial_manifest_*?

   run_manifest():
      - test all submitted variables:
         - ENVIRONMENT
            - including __debug, if debug
         - they are set
         - they contain the correct values
      - does $require work?
      - check that exception raised, if manifest is not existent

   object_run():
      - ensure no object is run twice
      - ensure requirements are taken into account?
         - and order of run is adjusted
      - check (from extern?) that all needed variables are setup
      - ensure no code-{local, remote} is created, 
         if gencode is not producing code
      - ensure THAT code-{local, remote} contains what gencode created
      - abort if gencode-* fails
      - abort if code-* fails
         - abort == raise(FooException)
      - gencode-*: ensure ENVIRONMENT is setup correctly

   run_type_explorer()
      - ensure ALL type explores have been run
      - ensure output is saved to correct path
      - ensure a type with {0,1,2} explorers works ?
         - none, one, multiple
      - ensure ENVIRONMENT is setup correctly
      - fails if ANY of the given explorer fails

   run_global_explorers():
      - ensure ALL type explores have been run
      - ensure output is saved to correct path
      - ensure a type with {0,1,2} explorers works ?
         - none, one, multiple
      - ensure ENVIRONMENT is setup correctly
      - fails if ANY of the given explorer fails
      
Code fixes needed:

   - shutil, os.mkdir, etc. everywhere: catch/reraise exceptions correctly
