        Configuration Extensions for Filtering or Inhibiting Configuration
        ==================================================================
        
        The zc.configuration package provides some configuration directives
        for inhibiting configuration.  The first of these is the excluse
        directive.  It is used to exclude processing of configuration
        files. It is usedful when including a configuration that includes some
        other configuration that you don't want.  It must be used before
        including the files to be excluded.
        
        First, let's look at an example.  The zope.configuration.demo package
        has a ZCML configuration that includes some other configuration files.
        
        We'll set a log handler so we can see what's going on:
        
        >>> import logging, sys
        >>> logger = logging.getLogger('config')
        >>> oldlevel = logger.level
        >>> logger.setLevel(logging.DEBUG)
        >>> handler = logging.StreamHandler(sys.stdout)
        >>> logger.addHandler(handler)
        
        Now, we'll include the zc.configuration.demo config:
        
        >>> from zope.configuration import xmlconfig
        >>> _ = xmlconfig.string('<include package="zc.configuration.demo" />')
        include /zc.configuration/src/zc/configuration/demo/configure.zcml
        include /zc.configuration/src/zc/configuration/demo/sub/configure.zcml
        include /zc.configuration/src/zc/configuration/demo/spam.zcml
        
        Each run of the configuration machinery runs with fresh state, so
        rerunning gives the same thing:
        
        >>> _ = xmlconfig.string('<include package="zc.configuration.demo" />')
        include /zc.configuration/src/zc/configuration/demo/configure.zcml
        include /zc.configuration/src/zc/configuration/demo/sub/configure.zcml
        include /zc.configuration/src/zc/configuration/demo/spam.zcml
        
        Now, we'll load the zc.configuration meta.zcml and use the exclude
        directive to include the two files included by the configuration file
        in zc.configuration.demo:
        
        >>> _ = xmlconfig.string(
        ... '''
        ... <configure  xmlns="http://namespaces.zope.org/zope">
        ...   <include package="zc.configuration" file="meta.zcml" />
        ...   <exclude package="zc.configuration.demo.sub" />
        ...   <exclude package="zc.configuration.demo" file="spam.zcml" />
        ...   <include package="zc.configuration.demo" />
        ... </configure>
        ... ''')
        include /zc.configuration/src/zc/configuration/meta.zcml
        include /zc.configuration/src/zc/configuration/demo/configure.zcml
        
        
        .. cleanup
        
        >>> logger.setLevel(oldlevel)
        >>> logger.removeHandler(handler)
