* convert to use python/egg.mk.
1.1 (2012-02-16)
----------------
* Fixed issue #326 - don't crash when a package's setup.py emits UTF-8 and
then fails. Thanks Marc Abramowitz.
* Added ``--target`` option for installing directly to arbitrary directory.
Thanks Stavros Korokithakis.
* Added support for authentication with Subversion repositories. Thanks
Qiangning Hong.
* Fixed issue #315 - ``--download`` now downloads dependencies as well.
Thanks Qiangning Hong.
* Errors from subprocesses will display the current working directory.
Thanks Antti Kaihola.
* Fixed issue #369 - compatibility with Subversion 1.7. Thanks Qiangning
Hong. Note that setuptools remains incompatible with Subversion 1.7; to
get the benefits of pip's support you must use Distribute rather than
setuptools.
* Fixed issue #57 - ignore py2app-generated OS X mpkg zip files in finder.
Thanks Rene Dudfield.
* Fixed issue #182 - log to ~/Library/Logs/ by default on OS X framework
installs. Thanks Dan Callahan for report and patch.
* Fixed issue #310 - understand version tags without minor version ("py3")
in sdist filenames. Thanks Stuart Andrews for report and Olivier Girardot for
patch.
* Fixed issue #7 - Pip now supports optionally installing setuptools
"extras" dependencies; e.g. "pip install Paste[openid]". Thanks Matt Maker
and Olivier Girardot.
* Fixed issue #391 - freeze no longer borks on requirements files with
--index-url or --find-links. Thanks Herbert Pfennig.
* Fixed issue #288 - handle symlinks properly. Thanks lebedov for the patch.
* Fixed issue #49 - pip install -U no longer reinstalls the same versions of
packages. Thanks iguananaut for the pull request.
* Removed ``-E`` option and ``PIP_RESPECT_VIRTUALENV``; both use a
restart-in-venv mechanism that's broken, and neither one is useful since
every virtualenv now has pip inside it.
* Fixed issue #366 - pip throws IndexError when it calls `scraped_rel_links`
* Fixed issue #22 - pip search should set and return a userful shell status code
* Fixed issue #351 and #365 - added global ``--exists-action`` command line
option to easier script file exists conflicts, e.g. from editable
requirements from VCS that have a changed repo URL.
techniques for finding packages, so packages that were made
easy_installable should be pip-installable as well.
pip is meant to improve on easy_install. Some of the improvements:
* All packages are downloaded before installation.
Partially-completed installation doesn't occur as a result.
* Care is taken to present useful output on the console.
* The reasons for actions are kept track of. For instance, if
a package is being installed, pip keeps track of why that package
was required.
* Error messages should be useful.
* The code is relatively concise and cohesive, making it easier
to use programmatically.
* Packages don't have to be installed as egg archives, they can
be installed flat (while keeping the egg metadata).
* Native support for other version control systems (Git, Mercurial
and Bazaar)
* Uninstallation of packages.
* Simple to define fixed sets of requirements and reliably
reproduce a set of packages.
