need to know the version scheme to use. This specifies
the current PEP-recommended scheme - use ``'legacy'``
if you need to support existing distributions on PyPI.

Choose one of two URLs where both are candidates for distribution
archives for the same version of a distribution (for example,
.tar.gz vs. zip).
The current implementation favours https:// URLs over http://, archives
from PyPI over those from other locations, wheel compatibility (if a
wheel) and then the archive name.

recursed into. If False, only the top-level directory
is searched,

Should a filename be considered as a candidate for a distribution
archive? As well as the filename, the directory which contains it
is provided, though not used by the current implementation.

This locator uses special extended metadata (not available on PyPI) and is
the basis of performant dependency resolution in distlib. Other locators
require archive downloads before dependencies can be determined! As you
might imagine, that can be slow.

the results from all locators are merged (this can be

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.
