``find_distributions(entry, True)`` is used to find distributions

always appended to ``.entries``, even if it is already present.
(This is because ``sys.path`` can contain the same value more than
once, and the ``.entries`` of the ``sys.path`` WorkingSet should always
equal ``sys.path``.)

This builds a similar dictionary to the zipimport directory
caches. However instead of tuples, ZipInfo objects are stored.
The translation of the tuple is as follows:
* [0] - zipinfo.filename on stock pythons this needs "/" --> os.sep
on pypy it is the same (one reason why distribute did work
in some cases on pypy and win32).
* [1] - zipinfo.compress_type
* [2] - zipinfo.compress_size
* [3] - zipinfo.file_size
* [4] - len(utf-8 encoding of filename) if zipinfo & 0x800
len(ascii encoding of filename) otherwise
* [5] - (zipinfo.date_time[0] - 1980) << 9 |
zipinfo.date_time[1] << 5 | zipinfo.date_time[2]
* [6] - (zipinfo.date_time[3] - 1980) << 11 |
zipinfo.date_time[4] << 5 | (zipinfo.date_time[5] // 2)
* [7] - zipinfo.CRC

This is a rough cross between distutils' StrictVersion and LooseVersion;
if you give it versions that would work with StrictVersion, then it behaves
the same; otherwise it acts like a slightly-smarter LooseVersion. It is
*possible* to create pathological version coding schemes that will fool
this parser, but they should be very rare in practice.
The returned value will be a tuple of strings. Numeric portions of the
version are padded to 8 digits so they will compare numerically, but
without relying on how numbers compare relative to strings. Dots are
dropped, but dashes are retained. Trailing zeros between alpha segments
or dashes are suppressed, so that e.g. "2.4.0" is considered the same as
"2.4". Alphanumeric parts are lower-cased.
The algorithm assumes that strings like "-" and any alpha string that
alphabetically follows "final" represents a "patch level". So, "2.4-1"
is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is
considered newer than "2.4-1", which in turn is newer than "2.4".
Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that
come before "final" alphabetically) are assumed to be pre-release versions,
so that the version "2.4" is considered newer than "2.4a1".
Finally, to handle miscellaneous cases, the strings "pre", "preview", and
"rc" are treated as if they were "c", i.e. as though they were release
candidates, and therefore are not as new as a version string that does not
contain them, and "dev" is replaced with an '@' so that it sorts lower than
than any other pre-release tag.

header, they're returned in a first ``section`` of ``None``.
