"""Resolve a dotted name to an object
A dotted name is constructed by concatenating a dotted module
name with a global name within the module using a dot. For
example, the object named "spam" in the foo.bar module has a
dotted name of foo.bar.spam. If the current package is a
prefix of a dotted name, then the package name can be relaced
with a leading dot, So, for example, if the configuration file
is in the foo package, then the dotted name foo.bar.spam can
be shortened to .bar.spam.
If the current package is multiple levels deep, multiple
leading dots can be used to refer to higher-level modules.
For example, if the current package is x.y.z, the dotted
object name ..foo refers to x.y.foo.

The job of most directives is to compute actions for later

conflict. Actions conflict if they have the same
discriminator. The exception to this is the special case of
the discriminator with the value None. An actions with a
discriminator of None never conflicts with other actions. This
is possible to add an order argument to crudely control the
order of execution. 'info' is optional source line information,
'includepath' is None (the default) or a tuple of include paths for
this action.
