`pkginfo` README

This package provides an API for querying the distutils metadata written in
the PKG-INFO file inside a source distribution (an sdist) or a
binary distribution (e.g., created by running bdist_egg). It can
also query the EGG-INFO directory of an installed distribution, and
the *.egg-info stored in a "development checkout"
(e.g, created by running setup.py develop).

Please see the pkginfo docs <http://packages.python.org/pkginfo>_
for detailed documentation.

Fix test failure under Python >= 2.7, which is enforcing
'metadata_version == 1.1' because we have classifiers.

0.9 (2012-04-25)

Fix introspection of installed namespace packages.
They may be installed as eggs or via dist-installed 'egg-info' files.
https://bugs.launchpad.net/pkginfo/+bug/934311
Avoid a regression in 0.8 under Python 2.6 / 2.7 when parsing unicode.
https://bugs.launchpad.net/pkginfo/+bug/733827/comments/3

0.8 (2011-03-12)

Work around Python 2.7's breakage of StringIO. Fixes
https://bugs.launchpad.net/pkginfo/+bug/733827
Fix bug in introspection of installed packages missing the
__package__ attribute.

Preserve newlines in the description field. Thanks to Sridhar
Ratnakumar for the patch.
100% test coverage.

0.6 (2010-06-01)

Replace use of StringIO.StringIO with io.StringIO, where available
(Python >= 2.6).
Replace use of rfc822 stdlib module with email.parser, when
available (Python >= 2.5). Ensured that distributions "unfold" wrapped
continuation lines, stripping any leading / trailing whitespace, no matter
which module was used for parsing.
Remove bogus testing dependency on zope.testing.
Add tests that the "environment markers" spelled out in the approved
PEP 345 are captured.

version of PEP 345).

Fix Trove metadata misspelling.
Restore compatibility with Python 2.4.
Note that the introspection of installed packages / modules works only
in Python 2.6 or later.
Add Index class as an abstraction over a collection of distributions.
Add download_url_prefix argument to pkginfo script. If passed,
the script will use the prefix to synthesize a download_url for
distributions which do not supply that value directly.

0.4.1 (2009-05-07)

Fix bugs in handling of installed packages which lack __file__
or PKG-INFO.

0.4 (2009-05-07)

Extend the console script to allow output as CSV or INI. Also, added
arguments to specify the metadata version and other parsing / output
policies.
Add support for the different metadata versions specified in PEPs
241, 314, and 345. Distributions now parse and expose only the attributes
corresponding to their metadata version, which defaults to the version
parsed from the PKG-INFO file. The programmer can override that version
when creating the distribution object.

0.3 (2009-05-07)

Add support for introspection of "development eggs" (checkouts with
PKG-INFO, perhaps created via setup.py develop).
Add a console script, pkginfo, which takes one or more paths
on the command line and writes out the associated information. Thanks
to runeh for the patch!
Add get_metadata helper function, which dispatches a given path or
module across the available distribution types, and returns a distribution
object. Thanks to runeh for the patch!
Make distribution objects support iteration over the metadata fields.
Thanks to runeh for the patch!
Make Distribution and subclasses new-style classes. Thanks to runeh
for the patch!

0.2 (2009-04-14)
