* merge - if False (the default), the first successful
search from any of the locators is returned. If True,
the results from all locators are merged (this can be
slow).

Attempt to replace one provider with another. This is typically used
when resolving dependencies from multiple sources, e.g. A requires
(B >= 1.0) while C requires (B >= 1.1).
For successful replacement, ``provider`` must meet all the requirements
which ``other`` fulfills.
:param provider: The provider we are trying to replace with.
:param other: The provider we're trying to replace.
:param problems: If False is returned, this will contain what
problems prevented replacement. This is currently
a tuple of the literal string 'cantreplace',
``provider``, ``other`` and the set of requirements
that ``provider`` couldn't fulfill.
:return: True if we can replace ``other`` with ``provider``, else
False.

Find a distribution and all distributions it depends on.
:param requirement: The requirement specifying the distribution to
find, or a Distribution instance.
:param meta_extras: A list of meta extras such as :test:, :build: and
so on.
:param prereleases: If ``True``, allow pre-release versions to be
returned - otherwise, don't return prereleases
unless they're all that's available.
Return a set of :class:`Distribution` instances and a set of
problems.
The distributions returned should be such that they have the
:attr:`required` attribute set to ``True`` if they were
from the ``requirement`` passed to ``find()``, and they have the
:attr:`build_time_dependency` attribute set to ``True`` unless they
are post-installation dependencies of the ``requirement``.
The problems should be a tuple consisting of the string
``'unsatisfied'`` and the requirement which couldn't be satisfied
by any distribution known to the locator.
