The *name* and *version* parameters are converted into their

with ``'_'`` other than the one in ``'dist-info'`` and the one
separating the name from the version number.
:parameter name: is converted to a standard distribution name by replacing
any runs of non- alphanumeric characters with a single
``'-'``.
:type name: string
:parameter version: is converted to a standard version string. Spaces
become dots, and all other non-alphanumeric characters
(except dots) become dashes, with runs of multiple
dashes condensed to a single dash.

mismatches. Each entry in the mismatch list will be a tuple consisting
of the path, 'exists', 'size' or 'hash' according to what didn't match
(existence is checked first, then size, then hash), the expected
value and the actual value.

Iterates over the ``installed-files.txt`` entries and returns paths for
each line if the path is pointing to a file located in the
``.egg-info`` directory or one of its subdirectories.
:parameter absolute: If *absolute* is ``True``, each returned path is
transformed into a local absolute path. Otherwise the
raw value from ``installed-files.txt`` is returned.
:type absolute: boolean

Represents a dependency graph between distributions.
The dependency relationships are stored in an ``adjacency_list`` that maps
distributions to a list of ``(other, label)`` tuples where ``other``
is a distribution and the edge is labeled with ``label`` (i.e. the version
specifier, if such was provided). Also, for more efficient traversal, for
every distribution ``x``, a list of predecessors is kept in
``reverse_list[x]``. An edge from distribution ``a`` to
distribution ``b`` means that ``a`` depends on ``b``. If any missing
dependencies are found, they are stored in ``missing``, which is a
dictionary that maps distributions to a list of requirements that were not
provided by any other distributions.
