What I mean by this is that, if you specify some handlers in the initial
configuration:
handlers:
console:
# configuration for a handler
file:
# configuration for a handler
email:
# configuration for a handler
then internally, there will be a map which has keys "console", "file" and
"email" pointing to the respective handlers. In a later incremental call,
you can do
handlers:
console:
level = ...
file:
level = ...
email:
level = ...
and the levels will be set on the handlers previously set up with the same
ids.
If you set up handlers programmatically and give them names:
h = logging.StreamHandler()
h.name = "console"
this will add an entry to the map with key "console" and a reference to h as
the value.
