#    updated by the app-specific router from applications/app/routes.py routers (if any)
#
#
#  Router members:
#
#  default_application: default application name
#  applications: list of all recognized applications, or 'ALL' to use all currently installed applications
#       Names in applications are always treated as an application names when they appear first in an incoming URL.
#       Set applications=None to disable the removal of application names from outgoing URLs.
#  domains: optional dict mapping domain names to application names
#       The domain name can include a port number: domain.com:8080
#       The application name can include a controller:  appx/ctlrx
#           or a controller and a function: appx/ctlrx/fcnx
#       Example:
#       domains = {   "domain.com" : "app",
#                  "x.domain.com" : "appx",
#                 },
#  path_prefix: a path fragment that is prefixed to all outgoing URLs and stripped from all incoming URLs
#
#  Note: default_application, applications, domains & path_prefix are permitted only in the BASE router,
#        and domain makes sense only in an application-specific router.
#        The remaining members can appear in the BASE router (as defaults for all applications)
#        or in application-specific routers.
#
#  default_controller: name of default controller
#  default_function: name of default function (in all controllers) or dictionary of default functions
#       by controller
#  controllers: list of valid controllers in selected app
#       or "DEFAULT" to use all controllers in the selected app plus 'static'
#       or None to disable controller-name removal.
#      Names in controllers are always treated as controller names when they appear in an incoming URL after
#      the (optional) application and language names.
#  functions: list of valid functions in the default controller (default None) or dictionary of valid
#       functions by controller.
#       If present, the default function name will be omitted when the controller is the default controller
#       and the first arg does not create an ambiguity.
#  languages: list of all supported languages
#       Names in languages are always treated as language names when they appear in an incoming URL after
#       the (optional) application name.
#  default_language
#       The language code (for example: en, it-it) optionally appears in the URL following
#       the application (which may be omitted). For incoming URLs, the code is copied to
#       request.language; for outgoing URLs it is taken from request.language.
#       If languages=None, language support is disabled.
#       The default_language, if any, is omitted from the URL.
#  root_static: list of static files accessed from root (by default, favicon.ico & robots.txt)
#       (mapped to the default application's static/ directory)
#       Each default (including domain-mapped) application has its own root-static files.
#  domain: the domain that maps to this application (alternative to using domains in the BASE router)
#  exclusive_domain: If True (default is False), an exception is raised if an attempt is made to generate
#       an outgoing URL with a different application without providing an explicit host.
#  map_hyphen: If True (default is False), hyphens in incoming /a/c/f fields are converted
#       to underscores, and back to hyphens in outgoing URLs.
#       Language, args and the query string are not affected.
#  map_static: By default, the default application is not stripped from static URLs.
#       Set map_static=True to override this policy.
#  acfe_match: regex for valid application, controller, function, extension /a/c/f.e
#  file_match: regex for valid file (used for static file names)
#  args_match: regex for valid args
#       This validation provides a measure of security.
#       If it is changed, the application perform its own validation.
#
#
#  The built-in default router supplies default values (undefined members are None):
#
#     default_router = dict(
#         default_application = 'init',
