Historically, setuptools would solicit and store 'extra'
requirements, including those with environment markers,
in separate sections. More modern tools expect each
dependency to be defined separately, with any relevant
extras and environment markers attached directly to that
requirement. This method converts the former to the
latter. See _test_deps_from_requires_text for an example.

|j f | S )a Return EntryPoint objects for all installed packages.
Pass selection parameters (group or name) to filter the
result to entry points matching those properties (see
EntryPoints.select()).
For compatibility, returns ``SelectableGroups`` object unless
selection parameters are supplied. In the future, this function
will return ``EntryPoints`` instead of ``SelectableGroups``
even when no selection parameters are supplied.
For maximum future compatibility, pass selection parameters
or invoke ``.select`` with parameters on the result.
:return: EntryPoints or SelectableGroups for all installed packages.
