+
+Management of configuration settings and preferences.
+
+  ($Id$)
+
+
+Setting up a loops Site and Utilities
+=====================================
+
+Let's do some basic set up
+
+  >>> from zope import component, interface
+  >>> from zope.traversing.api import getName
+  >>> from zope.app.testing.setup import placefulSetUp, placefulTearDown
+  >>> site = placefulSetUp(True)
+
+and build a simple loops site with a concept manager and some concepts
+(with a relation registry, a catalog, and all the type machinery - what
+in real life is done via standard ZCML setup or via local utility
+configuration):
+
+  >>> from loops.integrator.testsetup import TestSite
+  >>> t = TestSite(site)
+  >>> concepts, resources, views = t.setup()
+  >>> loopsRoot = concepts.getLoopsRoot()
+
+
+Options Adapters
+================
+
+Global and site options
+-----------------------
+
+  >>> from loops.config.base import LoopsOptions
+  >>> component.provideAdapter(LoopsOptions)
+
+  >>> from cybertools.meta.interfaces import IOptions
+  >>> opt = IOptions(loopsRoot)
+  >>> opt
+  <loops.config.base.LoopsOptions object ...>
+  >>> str(opt)
+  ''
+
+We now use the loops root object's options field to define
+some options.
+
+  >>> loopsRoot.options = ['useVersioning', 'organize.tracking:changes, access']
+  >>> opt = IOptions(loopsRoot)
+  >>> print opt
+  organize(tracking=['changes', 'access'])
+  useVersioning=True
+
+  >>> opt.organize.tracking
+  ['changes', 'access']
+  >>> opt.useVersioning
+  True
+
+If we query an option that is not defined on the site level we get a
+dummy element that corresponds to False.
+
+  >>> opt.i18n.languages
+  <AutoElement 'languages'>
+  >>> bool(opt.i18n.languages)
+  False
+
+
+Fin de partie
