The *name* and *version* parameters are converted into their
filename-escaped form, i.e. any ``'-'`` characters are replaced
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.

A dictionary of shared locations whose keys are in the set 'prefix',
'purelib', 'platlib', 'scripts', 'headers', 'data' and 'namespace'.
The corresponding value is the absolute path of that category for
this distribution, and takes into account any paths selected by the
user at installation time (e.g. via command-line arguments). In the
case of the 'namespace' key, this would be a list of absolute paths
for the roots of namespace packages in this distribution.
The first time this property is accessed, the relevant information is
read from the SHARED file in the .dist-info directory.

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.
