+# Python Buildpack Binaries
+
+
+To get started with it, create an app on Heroku inside a clone of this repository, and set your S3 config vars:
+
+    $ heroku create --buildpack https://github.com/heroku/heroku-buildpack-python#not-heroku
+    $ heroku config:set WORKSPACE_DIR=builds
+    $ heroku config:set AWS_ACCESS_KEY_ID=<your_aws_key>
+    $ heroku config:set AWS_SECRET_ACCESS_KEY=<your_aws_secret>
+    $ heroku config:set S3_BUCKET=<your_s3_bucket_name>
+
+
+Then, shell into an instance and run a build by giving the name of the formula inside `builds`:
+
+    $ heroku run bash
+    Running `bash` attached to terminal... up, run.6880
+    ~ $ bob build runtimes/python-2.7.6
+
+    Fetching dependencies... found 2:
+      - libraries/sqlite
+
+    Building formula runtimes/python-2.7.6:
+        === Building Python 2.7.6
+        Fetching Python v2.7.6 source...
+        Compiling...
+
+If this works, run `bob deploy` instead of `bob build` to have the result uploaded to S3 for you.
+
+To speed things up drastically, it'll usually be a good idea to `heroku run bash --size PX` instead.
+
+Enjoy :)

-Changelog
-=========
-
-1.5.2 (2014-01-26)
-------------------
-
-* Upgraded the vendored ``pkg_resources`` and ``_markerlib`` to setuptools 2.1.
-
-* Fixed an error that prevented accessing PyPI when pyopenssl, ndg-httpsclient,
-  and pyasn1 are installed
-
-* Fixed an issue that caused trailing comments to be incorrectly included as
-  part of the URL in a requirements file
-
-
-1.5.1 (2014-01-20)
-------------------
-
-* pip now only requires setuptools (any setuptools, not a certain version) when
-  installing distributions from src (i.e. not from wheel). (Pull #1434).
-
-* `get-pip.py` now installs setuptools, when it's not already installed (Pull
-  #1475)
-
-* Don't decode downloaded files that have a ``Content-Encoding`` header. (Pull
-  #1435)
-
-* Fix to correctly parse wheel filenames with single digit versions. (Pull
-  #1445)
-
-* If `--allow-unverified` is used assume it also means `--allow-external`. (Pull
-  #1457)
-
-
-
-1.5 (2014-01-01)
-----------------
-
-* **BACKWARD INCOMPATIBLE** pip no longer supports the ``--use-mirrors``,
-  ``-M``, and ``--mirrors`` flags. The mirroring support has been removed. In
-  order to use a mirror specify it as the primary index with ``-i`` or
-  ``--index-url``, or as an additional index with ``--extra-index-url``. (Pull #1098, CVE-2013-5123)
-
-* **BACKWARD INCOMPATIBLE** pip no longer will scrape insecure external urls by
-  default nor will it install externally hosted files by default. Users may opt
-  into installing externally hosted or insecure files or urls using
-  ``--allow-external PROJECT`` and ``--allow-unverified PROJECT``. (Pull #1055)
-
-* **BACKWARD INCOMPATIBLE** pip no longer respects dependency links by default.
-  Users may opt into respecting them again using ``--process-dependency-links``.
-
-* **DEPRECATION** ``pip install --no-install`` and ``pip install
-  --no-download`` are now formally deprecated.  See Issue #906 for discussion on
-  possible alternatives, or lack thereof, in future releases.
-
-* **DEPRECATION** ``pip zip`` and ``pip unzip`` are now formally deprecated.
-
-* pip will now install Mac OSX platform wheels from PyPI. (Pull #1278)
-
-* pip now generates the appropriate platform-specific console scripts when
-  installing wheels. (Pull #1251)
-
-* Pip now confirms a wheel is supported when installing directly from a path or
-  url. (Pull #1315)
-
-* Fixed #1097, ``--ignore-installed`` now behaves again as designed, after it was
-  unintentionally broke in v0.8.3 when fixing Issue #14 (Pull #1352).
-
-* Fixed a bug where global scripts were being removed when uninstalling --user
-  installed packages (Pull #1353).
-
-* Fixed #1163, --user wasn't being respected when installing scripts from wheels (Pull #1176).
-
-* Fixed #1150, we now assume '_' means '-' in versions from wheel filenames (Pull #1158).
-
-* Fixed #219, error when using --log with a failed install (Pull #1205).
-
-* Fixed #1131, logging was buffered and choppy in Python 3.
-
-* Fixed #70,  --timeout was being ignored (Pull #1202).
-
-* Fixed #772, error when setting PIP_EXISTS_ACTION (Pull #1201).
-
-* Added colors to the logging output in order to draw attention to important
-  warnings and errors. (Pull #1109)
-
-* Added warnings when using an insecure index, find-link, or dependency link. (Pull #1121)
-
-* Added support for installing packages from a subdirectory using the ``subdirectory``
-  editable option. ( Pull #1082 )
-
-* Fixed #1192. "TypeError: bad operand type for unary" in some cases when
-  installing wheels using --find-links (Pull #1218).
-
-* Fixed #1133 and #317. Archive contents are now written based on system
-  defaults and umask (i.e. permissions are not preserved), except that regular
-  files with any execute permissions have the equivalent of "chmod +x" applied
-  after being written (Pull #1146).
-
-* PreviousBuildDirError now returns a non-zero exit code and prevents the
-  previous build dir from being cleaned in all cases (Pull #1162).
-
-* Renamed --allow-insecure to --allow-unverified, however the old name will
-  continue to work for a period of time (Pull #1257).
-
-* Fixed #1006, error when installing local projects with symlinks in
-  Python 3. (Pull #1311)
-
-* The previously hidden ``--log-file`` otion, is now shown as a general option.
-  (Pull #1316)
-
-
-
-
-1.4.1 (2013-08-07)
-------------------
-
-* **New Signing Key** Release 1.4.1 is using a different key than normal with
-  fingerprint: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
-* Fixed issues with installing from pybundle files (Pull #1116).
-* Fixed error when sysconfig module throws an exception (Pull #1095).
-* Don't ignore already installed pre-releases (Pull #1076).
-* Fixes related to upgrading setuptools (Pull #1092).
-* Fixes so that --download works with wheel archives (Pull #1113).
-* Fixes related to recognizing and cleaning global build dirs (Pull #1080).
-
-
-1.4 (2013-07-23)
-----------------
-
-* **BACKWARD INCOMPATIBLE** pip now only installs stable versions by default,
-  and offers a new ``--pre`` option to also find pre-release and development
-  versions. (Pull #834)
-
-* **BACKWARD INCOMPATIBLE** Dropped support for Python 2.5. The minimum
-  supported Python version for pip 1.4 is Python 2.6.
-
-* Added support for installing and building wheel archives.
-  Thanks Daniel Holth, Marcus Smith, Paul Moore, and Michele Lacchia
-  (Pull #845)
-
-* Applied security patch to pip's ssl support related to certificate DNS
-  wildcard matching (http://bugs.python.org/issue17980).
-
-* To satisfy pip's setuptools requirement, pip now recommends setuptools>=0.8,
-  not distribute. setuptools and distribute are now merged into one project
-  called 'setuptools'. (Pull #1003)
-
-* pip will now warn when installing a file that is either hosted externally to
-  the index or cannot be verified with a hash. In the future pip will default
-  to not installing them and will require the flags --allow-external NAME, and
-  --allow-insecure NAME respectively. (Pull #985)
-
-* If an already-downloaded or cached file has a bad hash, re-download it rather
-  than erroring out. (Issue #963).
-
-* ``pip bundle`` and support for installing from pybundle files is now
-  considered deprecated and will be removed in pip v1.5.
-
-* Fixed a number of issues (#413, #709, #634, #602, and #939) related to
-  cleaning up and not reusing build directories. (Pull #865, #948)
-
-* Added a User Agent so that pip is identifiable in logs. (Pull #901)
-
-* Added ssl and --user support to get-pip.py. Thanks Gabriel de Perthuis.
-  (Pull #895)
-
-* Fixed the proxy support, which was broken in pip 1.3.x (Pull #840)
-
-* Fixed issue #32 - pip fails when server does not send content-type header.
-  Thanks Hugo Lopes Tavares and Kelsey Hightower (Pull #872).
-
-* "Vendorized" distlib as pip.vendor.distlib (https://distlib.readthedocs.org/).
-
-* Fixed git VCS backend with git 1.8.3. (Pull #967)
-
-1.3.1 (2013-03-08)
-------------------

-  available. Thanks Rafael Caricio, Miguel Araujo, Dmitry Gladkov (Pull #752)
-
-* Fixed security issues with pip's use of temp build directories.
-  Thanks David (d1b) and Thomas Guttler. (Pull #780, CVE-2013-1888)
-
-* Improvements to sphinx docs and cli help. (Pull #773)
-
-* Fixed issue #707, dealing with OS X temp dir handling, which was causing
-  global NumPy installs to fail. (Pull #768)
-
-* Split help output into general vs command-specific option groups.
-  Thanks Georgi Valkov. (Pull #744; Pull #721 contains preceding refactor)
-
-* Fixed dependency resolution when installing from archives with uppercase
-  project names. (Pull #724)
-
-* Fixed problem where re-installs always occurred when using file:// find-links.
-  (Pulls #683/#702)
-
-* "pip install -v" now shows the full download url, not just the archive name.
-  Thanks Marc Abramowitz (Pull #687)
-
-* Fix to prevent unnecessary PyPI redirects. Thanks Alex Gronholm (Pull #695)
-
-* Fixed issue #670 - install failure under Python 3 when the same version
-  of a package is found under 2 different URLs.  Thanks Paul Moore (Pull #671)
-
-* Fix git submodule recursive updates.  Thanks Roey Berman. (Pulls #674)
-
-* Explicitly ignore rel='download' links while looking for html pages.
-  Thanks Maxime R. (Pull #677)

-
-1.2.1 (2012-09-06)
-------------------

-  to ``pip install gmpy``; sdist filename must begin with full project name
-  followed by a dash. Thanks casevh for the report.
-
-* Fixed issue #504 - allow package URLS to have querystrings. Thanks W.
-  Trevor King.
-
-* Fixed issue #58 - pip freeze now falls back to non-editable format rather
-  than blowing up if it can't determine the origin repository of an editable.
-  Thanks Rory McCann.
-
-* Added a `__main__.py` file to enable `python -m pip` on Python versions
-  that support it. Thanks Alexey Luchko.
-

-
-* Added ``--target`` option for installing directly to arbitrary directory.
-  Thanks Stavros Korokithakis.

-  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.

-  in sdist filenames. Thanks Stuart Andrews for report and Olivier Girardot for
-  patch.

-  --index-url or --find-links. Thanks Herbert Pfennig.
-
-* Fixed issue #288 - handle symlinks properly. Thanks lebedov for the patch.
-

-  packages. Thanks iguananaut for the pull request.
-
-* Removed ``-E``/``--environment`` 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.  Replace ``pip -E
-  path/to/venv install Foo`` with ``virtualenv path/to/venv &&
-  path/to/venv/pip install Foo``.
-
-* 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.

-
-
-0.8
----
-
-* Track which ``build/`` directories pip creates, never remove directories
-  it doesn't create.  From Hugo Lopes Tavares.
-
-* Pip now accepts file:// index URLs. Thanks Dave Abrahams.
-
-* Various cleanup to make test-running more consistent and less fragile.
-  Thanks Dave Abrahams.
-
-* Real Windows support (with passing tests). Thanks Dave Abrahams.
-
-* ``pip-2.7`` etc. scripts are created (Python-version specific scripts)
-
-* ``contrib/build-standalone`` script creates a runnable ``.zip`` form of
-  pip, from Jannis Leidel
-
-* Editable git repos are updated when reinstalled
-
-* Fix problem with ``--editable`` when multiple ``.egg-info/`` directories
-  are found.
-
-* A number of VCS-related fixes for ``pip freeze``, from Hugo Lopes Tavares.
-
-* Significant test framework changes, from Hugo Lopes Tavares.
-
-0.7.2
------
-
-* Set zip_safe=False to avoid problems some people are encountering where
-  pip is installed as a zip file.
-
-0.7.1
------
-
-* Fixed opening of logfile with no directory name. Thanks Alexandre Conrad.
-
-* Temporary files are consistently cleaned up, especially after
-  installing bundles, also from Alex Conrad.
-
-* Tests now require at least ScriptTest 1.0.3.
-
-0.7
----
-
-* Fixed uninstallation on Windows
-* Added ``pip search`` command.
-* Tab-complete names of installed distributions for ``pip uninstall``.
-* Support tab-completion when there is a global-option before the
-  subcommand.
-* Install header files in standard (scheme-default) location when installing
-  outside a virtualenv. Install them to a slightly more consistent
-  non-standard location inside a virtualenv (since the standard location is
-  a non-writable symlink to the global location).
-* pip now logs to a central location by default (instead of creating
-  ``pip-log.txt`` all over the place) and constantly overwrites the
-  file in question. On Unix and Mac OS X this is ``'$HOME/.pip/pip.log'``
-  and on Windows it's ``'%HOME%\\pip\\pip.log'``. You are still able to
-  override this location with the ``$PIP_LOG_FILE`` environment variable.
-  For a complete (appended) logfile use the separate ``'--log'`` command line
-  option.
-* Fixed an issue with Git that left an editable packge as a checkout of a
-  remote branch, even if the default behaviour would have been fine, too.
-* Fixed installing from a Git tag with older versions of Git.
-* Expand "~" in logfile and download cache paths.
-* Speed up installing from Mercurial repositories by cloning without
-  updating the working copy multiple times.
-* Fixed installing directly from directories (e.g.
-  ``pip install path/to/dir/``).
-* Fixed installing editable packages with ``svn+ssh`` URLs.
-* Don't print unwanted debug information when running the freeze command.
-* Create log file directory automatically. Thanks Alexandre Conrad.
-* Make test suite easier to run successfully. Thanks Dave Abrahams.
-* Fixed "pip install ." and "pip install .."; better error for directory
-  without setup.py. Thanks Alexandre Conrad.
-* Support Debian/Ubuntu "dist-packages" in zip command. Thanks duckx.
-* Fix relative --src folder. Thanks Simon Cross.
-* Handle missing VCS with an error message. Thanks Alexandre Conrad.
-* Added --no-download option to install; pairs with --no-install to separate
-  download and installation into two steps. Thanks Simon Cross.
-* Fix uninstalling from requirements file containing -f, -i, or
-  --extra-index-url.
-* Leftover build directories are now removed. Thanks Alexandre Conrad.

-  Mercurial and ``ftp`` scheme to the Bazaar backend.
-
-* Fixed uninstallation of scripts installed with easy_install.
-
-* Fixed an issue in the package finder that could result in an
-  infinite loop while looking for links.
-
-* Fixed issue with ``pip bundle`` and local files (which weren't being
-  copied into the bundle), from Whit Morriss.
-
-0.6
----
-
-* Add ``pip uninstall`` and uninstall-before upgrade (from Carl
-  Meyer).
-
-* Extended configurability with config files and environment variables.
-
-* Allow packages to be upgraded, e.g., ``pip install Package==0.1``
-  then ``pip install Package==0.2``.
-
-* Allow installing/upgrading to Package==dev (fix "Source version does not
-  match target version" errors).
-
-* Added command and option completion for bash and zsh.
-
-* Extended integration with virtualenv by providing an option to
-  automatically use an active virtualenv and an option to warn if no active
-  virtualenv is found.
-
-* Fixed a bug with pip install --download and editable packages, where
-  directories were being set with 0000 permissions, now defaults to 755.
-
-* Fixed uninstallation of easy_installed console_scripts.
-
-* Fixed uninstallation on Mac OS X Framework layout installs
-
-* Fixed bug preventing uninstall of editables with source outside venv.
-

-
-0.5.1
------
-
-* Fixed a couple little bugs, with git and with extensions.
-
-0.5
----
-
-* Added ability to override the default log file name (``pip-log.txt``)
-  with the environmental variable ``$PIP_LOG_FILE``.
-
-* Made the freeze command print installed packages to stdout instead of
-  writing them to a file. Use simple redirection (e.g.
-  ``pip freeze > stable-req.txt``) to get a file with requirements.
-
-* Fixed problem with freezing editable packages from a Git repository.
-
-* Added support for base URLs using ``<base href='...'>`` when parsing
-  HTML pages.
-
-* Fixed installing of non-editable packages from version control systems.
-
-* Fixed issue with Bazaar's bzr+ssh scheme.
-
-* Added --download-dir option to the install command to retrieve package
-  archives. If given an editable package it will create an archive of it.
-
-* Added ability to pass local file and directory paths to ``--find-links``,
-  e.g. ``--find-links=file:///path/to/my/private/archive``
-
-* Reduced the amount of console log messages when fetching a page to find a
-  distribution was problematic. The full messages can be found in pip-log.txt.
-
-* Added ``--no-deps`` option to install ignore package dependencies
-
-* Added ``--no-index`` option to ignore the package index (PyPI) temporarily
-
-* Fixed installing editable packages from Git branches.
-
-* Fixes freezing of editable packages from Mercurial repositories.
-
-* Fixed handling read-only attributes of build files, e.g. of Subversion and
-  Bazaar on Windows.
-
-* When downloading a file from a redirect, use the redirected
-  location's extension to guess the compression (happens specifically
-  when redirecting to a bitbucket.org tip.gz file).
-
-* Editable freeze URLs now always use revision hash/id rather than tip or
-  branch names which could move.
-
-* Fixed comparison of repo URLs so incidental differences such as
-  presence/absence of final slashes or quoted/unquoted special
-  characters don't trigger "ignore/switch/wipe/backup" choice.
-
-* Fixed handling of attempt to checkout editable install to a
-  non-empty, non-repo directory.
-
-0.4
----
-
-* Make ``-e`` work better with local hg repositories
-
-* Construct PyPI URLs the exact way easy_install constructs URLs (you
-  might notice this if you use a custom index that is
-  slash-sensitive).
-
-* Improvements on Windows (from `Ionel Maries Cristian
-  <http://ionelmc.wordpress.com/>`_).
-
-* Fixed problem with not being able to install private git repositories.
-
-* Make ``pip zip`` zip all its arguments, not just the first.
-
-* Fix some filename issues on Windows.
-
-* Allow the ``-i`` and ``--extra-index-url`` options in requirements
-  files.
-
-* Fix the way bundle components are unpacked and moved around, to make
-  bundles work.
-
-* Adds ``-s`` option to allow the access to the global site-packages if a
-  virtualenv is to be created.
-
-* Fixed support for Subversion 1.6.
-
-0.3.1
------
-
-* Improved virtualenv restart and various path/cleanup problems on win32.
-
-* Fixed a regression with installing from svn repositories (when not
-  using ``-e``).
-
-* Fixes when installing editable packages that put their source in a
-  subdirectory (like ``src/``).
-
-* Improve ``pip -h``
-
-0.3
----
-
-* Added support for editable packages created from Git, Mercurial and Bazaar
-  repositories and ability to freeze them. Refactored support for version
-  control systems.
-
-* Do not use ``sys.exit()`` from inside the code, instead use a
-  return.  This will make it easier to invoke programmatically.
-
-* Put the install record in ``Package.egg-info/installed-files.txt``
-  (previously they went in
-  ``site-packages/install-record-Package.txt``).
-
-* Fix a problem with ``pip freeze`` not including ``-e svn+`` when an
-  svn structure is peculiar.
-
-* Allow ``pip -E`` to work with a virtualenv that uses a different
-  version of Python than the parent environment.
-
-* Fixed Win32 virtualenv (``-E``) option.
-
-* Search the links passed in with ``-f`` for packages.
-
-* Detect zip files, even when the file doesn't have a ``.zip``
-  extension and it is served with the wrong Content-Type.
-
-* Installing editable from existing source now works, like ``pip
-  install -e some/path/`` will install the package in ``some/path/``.
-  Most importantly, anything that package requires will also be
-  installed by pip.
-
-* Add a ``--path`` option to ``pip un/zip``, so you can avoid zipping
-  files that are outside of where you expect.
-
-* Add ``--simulate`` option to ``pip zip``.
-
-0.2.1
------
-
-* Fixed small problem that prevented using ``pip.py`` without actually
-  installing pip.
-
-* Fixed ``--upgrade``, which would download and appear to install
-  upgraded packages, but actually just reinstall the existing package.
-
-* Fixed Windows problem with putting the install record in the right
-  place, and generating the ``pip`` script with Setuptools.
-
-* Download links that include embedded spaces or other unsafe
-  characters (those characters get %-encoded).
-
-* Fixed use of URLs in requirement files, and problems with some blank
-  lines.
-
-* Turn some tar file errors into warnings.
-
-0.2
----
-
-* Renamed to ``pip``, and to install you now do ``pip install
-  PACKAGE``
-
-* Added command ``pip zip PACKAGE`` and ``pip unzip PACKAGE``.  This
-  is particularly intended for Google App Engine to manage libraries
-  to stay under the 1000-file limit.
-
-* Some fixes to bundles, especially editable packages and when
-  creating a bundle using unnamed packages (like just an svn
-  repository without ``#egg=Package``).
-
-0.1.4
------
-
-* Added an option ``--install-option`` to pass options to pass
-  arguments to ``setup.py install``
-
-* ``.svn/`` directories are no longer included in bundles, as these
-  directories are specific to a version of svn -- if you build a
-  bundle on a system with svn 1.5, you can't use the checkout on a
-  system with svn 1.4.  Instead a file ``svn-checkout.txt`` is
-  included that notes the original location and revision, and the
-  command you can use to turn it back into an svn checkout.  (Probably
-  unpacking the bundle should, maybe optionally, recreate this
-  information -- but that is not currently implemented, and it would
-  require network access.)
-
-* Avoid ambiguities over project name case, where for instance
-  MyPackage and mypackage would be considered different packages.
-  This in particular caused problems on Macs, where ``MyPackage/`` and
-  ``mypackage/`` are the same directory.
-
-* Added support for an environmental variable
-  ``$PIP_DOWNLOAD_CACHE`` which will cache package downloads, so
-  future installations won't require large downloads.  Network access
-  is still required, but just some downloads will be avoided when
-  using this.
-
-0.1.3
------
-
-* Always use ``svn checkout`` (not ``export``) so that
-  ``tag_svn_revision`` settings give the revision of the package.
-
-* Don't update checkouts that came from ``.pybundle`` files.
-
-0.1.2
------
-
-* Improve error text when there are errors fetching HTML pages when
-  seeking packages.
-
-* Improve bundles: include empty directories, make them work with
-  editable packages.
-
-* If you use ``-E env`` and the environment ``env/`` doesn't exist, a
-  new virtual environment will be created.
-
-* Fix ``dependency_links`` for finding packages.
-
-0.1.1
------
-
-* Fixed a NameError exception when running pip outside of a
-  virtualenv environment.
-
-* Added HTTP proxy support (from Prabhu Ramachandran)
-
-* Fixed use of ``hashlib.md5`` on python2.5+ (also from Prabhu
-  Ramachandran)
-
-0.1

-.. _`Configuration`:
-
-Configuration
-=================
-
-.. _config-file:
-
-Config file
-------------
-
-pip allows you to set all command line option defaults in a standard ini
-style config file.
-
-The names and locations of the configuration files vary slightly across
-platforms.
-
-* On Unix and Mac OS X the configuration file is: :file:`$HOME/.pip/pip.conf`
-* On Windows, the configuration file is: :file:`%HOME%\\pip\\pip.ini`
-
-You can set a custom path location for the config file using the environment variable ``PIP_CONFIG_FILE``.
-
-The names of the settings are derived from the long command line option, e.g.
-if you want to use a different package index (``--index-url``) and set the
-HTTP timeout (``--default-timeout``) to 60 seconds your config file would
-look like this:
-
-.. code-block:: ini
-
-    [global]
-    timeout = 60
-    index-url = http://download.zope.org/ppix
-
-Each subcommand can be configured optionally in its own section so that every
-global setting with the same name will be overridden; e.g. decreasing the
-``timeout`` to ``10`` seconds when running the `freeze`
-(`Freezing Requirements <./#freezing-requirements>`_) command and using
-``60`` seconds for all other commands is possible with:
-
-.. code-block:: ini
-
-    [global]
-    timeout = 60
-
-    [freeze]
-    timeout = 10
-
-
-Boolean options like ``--ignore-installed`` or ``--no-dependencies`` can be
-set like this:
-
-.. code-block:: ini
-
-    [install]
-    ignore-installed = true
-    no-dependencies = yes
-
-Appending options like ``--find-links`` can be written on multiple lines:
-
-.. code-block:: ini
-
-    [global]
-    find-links =
-        http://download.example.com
-
-    [install]
-    find-links =
-        http://mirror1.example.com
-        http://mirror2.example.com
-
-
-Environment Variables
----------------------
-
-pip's command line options can be set with
-environment variables using the format ``PIP_<UPPER_LONG_NAME>`` . Dashes (``-``) have to replaced with underscores (``_``).
-
-For example, to set the default timeout::
-
-    export PIP_DEFAULT_TIMEOUT=60
-
-This is the same as passing the option to pip directly::
-
-    pip --default-timeout=60 [...]
-
-To set options that can be set multiple times on the command line, just add spaces in between values. For example::
-
-    export PIP_FIND_LINKS="http://mirror1.example.com http://mirror2.example.com"
-
-is the same as calling::
-
-    pip install --find-links=http://mirror1.example.com --find-links=http://mirror2.example.com
-
-
-Config Precedence
------------------
-
-Command line options have precedence over environment variables, which have precedence over the config file.
-
-Within the config file, command specific sections have precedence over the global section.
-
-Examples:
-
-- ``--host=foo`` overrides ``PIP_HOST=foo``
-- ``PIP_HOST=foo`` overrides a config file with ``[global] host = foo``
-- A command specific section in the config file ``[<command>] host = bar``
-  overrides the option with same name in the ``[global]`` config file section
-
-
-Command Completion
-------------------
-
-pip comes with support for command line completion in bash and zsh.
-
-To setup for bash::
-
-    $ pip completion --bash >> ~/.profile
-
-To setup for zsh::
-
-    $ pip completion --zsh >> ~/.zprofile
-
-Alternatively, you can use the result of the ``completion`` command
-directly with the eval function of you shell, e.g. by adding the following to your startup file::
-
-    eval "`pip completion --bash`"

-
-.. _`Requirements Files`:
-
-Requirements Files
-******************
-
-"Requirements files" are files containing a list of items to be
-installed using :ref:`pip install -r <install_--requirement>` like so:
-
- ::
-
-   pip install -r requirements.txt
-
-
-Details on the format of the files are here: :ref:`Requirements File Format`.
-
-
-There are 3 common use cases for requirements files:
-
-1. When installing many things, it's easier to use a requirements file,
-   than specifying them all on the command line.
-
-2. Requirements files are often used to hold the result from :ref:`pip freeze`
-   for the purpose of achieving :ref:`repeatable installations <Repeatability>`.
-   In this case, your requirement file contains a pinned version of everything
-   that was installed when `pip freeze` was run.
-
-   ::
-
-     pip freeze > requirements.txt
-     pip install -r requirements.txt
-
-3. Requirements files can be used to force pip to properly resolve dependencies.
-   As it is now, pip `doesn't have true dependency resolution
-   <https://github.com/pypa/pip/issues/988>`_, but instead simply uses the first
-   specification it finds for a project. E.g if `pkg1` requires `pkg3>=1.0` and
-   `pkg2` requires `pkg3>=1.0,<=2.0`, and if `pkg1` is resolved first, pip will
-   only use `pkg3>=1.0`, and could easily end up installing a version of `pkg3`
-   that conflicts with the needs of `pkg2`.  To solve this problem, you can
-   place `pkg3>=1.0,<=2.0` (i.e. the correct specification) into your
-   requirements file directly along with the other top level requirements. Like
-   so:
-
-   ::
-
-     pkg1
-     pkg2
-     pkg3>=1.0,<=2.0
-
-
-It's important to be clear that pip determines package dependencies using `install_requires metadata
-<http://pythonhosted.org/setuptools/setuptools.html#declaring-dependencies>`_, not by discovering `requirements.txt`
-files embedded in projects.
-
-For a good discussion on the conceptual differences between setup.py and
-requirements, see `"setup.py vs requirements.txt" (an article by Donald Stufft)
-<https://caremad.io/blog/setup-vs-requirement/>`_
-
-See also:
-
-* :ref:`Requirements File Format`
-* :ref:`pip freeze`
-
-
-.. _`Fast & Local Installs`:
-
-Fast & Local Installs
-*********************
-
-Often, you will want a fast install from local archives, without probing PyPI.
-
-First, :ref:`download the archives <Downloading Archives>` that fulfill your requirements::
-
-$ pip install --download <DIR> -r requirements.txt
-
-Then, install using  :ref:`--find-links <--find-links>` and :ref:`--no-index <--no-index>`::
-
-$ pip install --no-index --find-links=[file://]<DIR> -r requirements.txt
-
-
-.. _`Building and Installing Wheels`:
-
-Building and Installing Wheels
-******************************
-
-"Wheel" is a built, archive format that can greatly speed installation compared
-to building and installing from source archives. For more information, see the
-`Wheel docs <http://wheel.readthedocs.org>`_ ,
-`PEP427 <http://www.python.org/dev/peps/pep-0427>`_, and
-`PEP425 <http://www.python.org/dev/peps/pep-0425>`_
-
-Pip prefers Wheels where they are available, to disable this use the
-:ref:`--no-use-wheel <install_--no-use-wheel>` flag for :ref:`pip install`.
-
-If no satisfactory wheels are found, pip will default to finding source archives.
-
-.. note::
-
-  pip currently disallows platform-specific wheels (except for Windows and Mac)
-  from being downloaded from PyPI.  See :ref:`Should you upload wheels to PyPI`.
-
-
-To install directly from a wheel archive:
-
-::
-
- pip install SomePackage-1.0-py2.py3-none-any.whl
-
-
-pip additionally offers :ref:`pip wheel` as a convenience, to build wheels for
-your requirements and dependencies.
-
-:ref:`pip wheel` requires the `wheel package <https://pypi.python.org/pypi/wheel>`_ to be installed,
-which provides the "bdist_wheel" setuptools extension that it uses.
-
-To build wheels for your requirements and all their dependencies to a local directory:
-
-::
-
- pip install wheel
- pip wheel --wheel-dir=/local/wheels -r requirements.txt
-
-
-.. warning::
-
-  Currently, when ``pip wheel`` finds a wheel for one of your requirements
-  already on PyPI, it does not rebuild, and it does not place the file in your
-  wheelhouse dir.  There is an issue open to change this
-  (https://github.com/pypa/pip/issues/1310)
-
-
-
-And *then* to install those requirements just using your local directory of wheels (and not from PyPI):
-
-::
-
- pip install --no-index --find-links=/local/wheels -r requirements.txt
-
-
-.. _`Should you upload wheels to PyPI`:
-
-Should you upload wheels to PyPI?
----------------------------------
-
-The wheel format can eliminate a lot of redundant compilation but, alas,
-it's not generally advisable to upload your pre-compiled linux-x86-64
-library binding to pypi. Wheel's tags are only designed to express
-the most important *Python*-specific compatibility concerns (Python
-version, ABI, and architecture) but do not represent other important
-binary compatibility factors such as the OS release, patch level, and
-the versions of all the shared library dependencies of any extensions
-inside the package.
-
-Rather than representing all possible compatibility information in the
-wheel itself, the wheel design suggests distribution-specific build
-services (e.g. a separate index for Fedora Linux binary wheels, compiled
-by the index maintainer). This is the same solution taken by Linux
-distributions which all re-compile their own packages instead of installing
-each other's binary packages.
-
-Some kinds of precompiled C extension modules can make sense on PyPI, even
-for Linux. Good examples include things that can be sensibly statically
-linked (a cryptographic hash function; an accelerator module that is
-not a binding for an external library); the best example of something
-that shouldn't be statically linked is a library like openssl that needs
-to be constantly kept up-to-date for security. Regardless of whether a
-compatible pre-build package is available, many Linux users will prefer
-to always compile their own anyway.
-
-On Windows and Mac, the case for binary wheels on pypi is stronger due to the
-systems being much more uniform than Linux and because it's harder for the end
-user to compile their own. Windows and Mac wheels uploaded to pypi should be
-compatible with the Python distributions downloaded from http://python.org/.  If
-you already upload other binary formats to pypi, upload wheels as well.  Unlike
-the older formats, wheels are compatible with virtual environments.
-
-
-.. _`Downloading Archives`:
-
-Downloading archives
-********************
-
-pip allows you to *just* download the source archives for your requirements, without installing anything and without regard to what's already installed.
-
-::
-
-$ pip install --download <DIR> -r requirements.txt
-
-or, for a specific package::
-
-$ pip install --download <DIR> SomePackage
-
-
-Unpacking archives
-******************
-
-pip allows you to *just* unpack archives to a build directory without installing them to site-packages.  This can be useful to troubleshoot install errors or to inspect what is being installed.
-
-::
-
-$ pip install --no-install SomePackage
-
-If you're in a virtualenv, the build dir is ``<virtualenv path>/build``.  Otherwise, it's ``<OS temp dir>/pip-build-<username>``
-
-Afterwards, to finish the job of installing unpacked archives, run::
-
-$ pip install --no-download SomePackage
-
-
-
-Non-recursive upgrades
-************************
-
-``pip install --upgrade`` is currently written to perform a recursive upgrade.
-
-E.g. supposing:
-
-* `SomePackage-1.0` requires `AnotherPackage>=1.0`
-* `SomePackage-2.0` requires `AnotherPackage>=1.0` and `OneMorePoject==1.0`
-* `SomePackage-1.0` and `AnotherPackage-1.0` are currently installed
-* `SomePackage-2.0` and `AnotherPackage-2.0` are the latest versions available on PyPI.
-
-Running ``pip install --upgrade SomePackage`` would upgrade `SomePackage` *and* `AnotherPackage`
-despite `AnotherPackage` already being satisifed.
-
-If you would like to perform a non-recursive upgrade perform these 2 steps::
-
-  pip install --upgrade --no-deps SomePackage
-  pip install SomePackage
-
-The first line will upgrade `SomePackage`, but not dependencies like `AnotherPackage`.  The 2nd line will fill in new dependencies like `OneMorePackage`.
-
-
-.. _`Repeatability`:
-
-Ensuring Repeatability
-**********************
-
-Three things are required to fully guarantee a repeatable installation using requirements files.
-
-1. The requirements file was generated by ``pip freeze`` or you're sure it only
-   contains requirements that specify a specific version.
-2. The installation is performed using :ref:`--no-deps <install_--no-deps>`.
-   This guarantees that only what is explicitly listed in the requirements file is
-   installed.
-3. The installation is performed against an index or find-links location that is
-   guaranteed to *not* allow archives to be changed and updated without a
-   version increase.  Unfortunately, this is *not* true on PyPI. It is possible
-   for the same pypi distribution to have a different hash over time. Project
-   authors are allowed to delete a distribution, and then upload a new one with
-   the same name and version, but a different hash. See `Issue #1175
-   <https://github.com/pypa/pip/issues/1175>`_ for plans to add hash
-   confirmation to pip, or a new "lock file" notion, but for now, know that the `peep
-   project <https://pypi.python.org/pypi/peep>`_ offers this feature on top of pip
-   using requirements file comments.
-
-User Installs
-*************
-
-With Python 2.6 came the `"user scheme" for installation
-<http://docs.python.org/install/index.html#alternate-installation-the-user-scheme>`_, which means that all
-Python distributions support an alternative install location that is specific to a user.
-The default location for each OS is explained in the python documentation
-for the `site.USER_BASE <http://docs.python.org/library/site.html#site.USER_BASE>`_ variable.
-This mode of installation can be turned on by
-specifying the :ref:`--user <install_--user>` option to ``pip install``.
-
-Moreover, the "user scheme" can be customized by setting the
-``PYTHONUSERBASE`` environment variable, which updates the value of ``site.USER_BASE``.
-
-To install "SomePackage" into an environment with site.USER_BASE customized to '/myappenv', do the following::
-
-    export PYTHONUSERBASE=/myappenv
-    pip install --user SomePackage
-
-
-``pip install --user`` follows four rules:
-
-#. When globally installed packages are on the python path, and they *conflict*
-   with the installation requirements, they are ignored, and *not*
-   uninstalled.
-#. When globally installed packages are on the python path, and they *satisfy*
-   the installation requirements, pip does nothing, and reports that
-   requirement is satisfied (similar to how global packages can satisfy
-   requirements when installing packages in a ``--system-site-packages``
-   virtualenv).
-#. pip will not perform a ``--user`` install in a ``--no-site-packages``
-   virtualenv (i.e. the default kind of virtualenv), due to the user site not
-   being on the python path.  The installation would be pointless.
-#. In a ``--system-site-packages`` virtualenv, pip will not install a package
-   that conflicts with a package in the virtualenv site-packages.  The --user
-   installation would lack sys.path precedence and be pointless.
-
-
-To make the rules clearer, here are some examples:
-
-
-From within a ``--no-site-packages`` virtualenv (i.e. the default kind)::
-
-  $ pip install --user SomePackage
-  Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
-
-
-From within a ``--system-site-packages`` virtualenv where ``SomePackage==0.3`` is already installed in the virtualenv::
-
-  $ pip install --user SomePackage==0.4
-  Will not install to the user site because it will lack sys.path precedence
-
-
-From within a real python, where ``SomePackage`` is *not* installed globally::
-
-  $ pip install --user SomePackage
-  [...]
-  Successfully installed SomePackage
-
-
-From within a real python, where ``SomePackage`` *is* installed globally, but is *not* the latest version::
-
-  $ pip install --user SomePackage
-  [...]
-  Requirement already satisfied (use --upgrade to upgrade)
-
-  $ pip install --user --upgrade SomePackage
-  [...]
-  Successfully installed SomePackage
-
-
-From within a real python, where ``SomePackage`` *is* installed globally, and is the latest version::
-
-  $ pip install --user SomePackage
-  [...]
-  Requirement already satisfied (use --upgrade to upgrade)
-
-  $ pip install --user --upgrade SomePackage
-  [...]
-  Requirement already up-to-date: SomePackage
-
-  # force the install
-  $ pip install --user --ignore-installed SomePackage
-  [...]
-  Successfully installed SomePackage
-
-
-
-Controlling setup_requires
-**************************
-
-Setuptools offers the ``setup_requires``
-`setup() keyword <http://pythonhosted.org/setuptools/setuptools.html#new-and-changed-setup-keywords>`_
-for specifying dependencies that need to be present in order for the `setup.py` script to run.
-Internally, Setuptools uses ``easy_install`` to fulfill these dependencies.
-
-pip has no way to control how these dependencies are located.
-None of the :ref:`Package Index Options <Package Index Options>` have an effect.
-
-The solution is to configure a "system" or "personal"
-`Distutils configuration file <http://docs.python.org/2/install/index.html#distutils-configuration-files>`_
-to manage the fulfillment.
-
-For example, to have the dependency located at an alternate index, add this:
-
-::
-
-  [easy_install]
-  index_url = https://my.index-mirror.com
-
-To have the dependency located from a local directory and not crawl PyPI, add this:
-
-::
-
-  [easy_install]
-  allow_hosts = ''
-  find_links = file:///path/to/local/archives
-
-
-Upgrading from distribute to setuptools
-***************************************
-
-`distribute`_ has now been merged into `setuptools`_, and it is recommended to upgrade to setuptools when possible.
-
-To upgrade from `distribute`_ to `setuptools`_ using pip, run::
-
-  pip install --upgrade setuptools
-
-"ImportError: No module named setuptools"
------------------------------------------
-
-Although using the upgrade command above works in isolation, it's possible to get
-"ImportError: No module named setuptools" when using pip<1.4 to upgrade a
-package that depends on setuptools or distribute.
-
-e.g. when running a command like this:  `pip install --upgrade pyramid`
-
-Solution
-~~~~~~~~
-
-To prevent the problem in *new* environments (that aren't broken yet):
-
-* Option 1:
-
- * *First* run `pip install -U setuptools`,
- * *Then* run the command to upgrade your package (e.g. `pip install --upgrade pyramid`)
-
-* Option 2:
-
- * Upgrade pip using :ref:`get-pip <get-pip>`
- * *Then* run the command to upgrade your package (e.g. `pip install --upgrade pyramid`)
-
-To fix the problem once it's occurred, you'll need to manually install the new
-setuptools, then rerun the upgrade that failed.
-
-1. Download `ez_setup.py` (https://bitbucket.org/pypa/setuptools/downloads/ez_setup.py)
-2. Run `python ez_setup.py`
-3. Then rerun your upgrade (e.g. `pip install --upgrade pyramid`)
-
-
-Cause
-~~~~~
-
-distribute-0.7.3 is just an empty wrapper that only serves to require the new
-setuptools (setuptools>=0.7) so that it will be installed. (If you don't know
-yet, the "new setuptools" is a merge of distribute and setuptools back into one
-project).
-
-distribute-0.7.3 does its job well, when the upgrade is done in isolation.
-E.g. if you're currently on distribute-0.6.X, then running `pip install -U
-setuptools` works fine to upgrade you to setuptools>=0.7.
-
-The problem occurs when:
-
-1. you are currently using an older distribute (i.e. 0.6.X)
-2. and you try to use pip to upgrade a package that *depends* on setuptools or
-   distribute.
-
-As part of the upgrade process, pip builds an install list that ends up
-including distribute-0.7.3 and setuptools>=0.7 , but they can end up being
-separated by other dependencies in the list, so what can happen is this:
-
-1.  pip uninstalls the existing distribute
-2.  pip installs distribute-0.7.3 (which has no importable setuptools, that pip
-    *needs* internally to function)
-3.  pip moves on to install another dependency (before setuptools>=0.7) and is
-    unable to proceed without the setuptools package
-
-Note that pip v1.4 has fixes to prevent this.  distribute-0.7.3 (or
-setuptools>=0.7) by themselves cannot prevent this kind of problem.

-Submit Pull Requests against the `develop` branch.
-
-Provide a good description of what you're doing and why.
-
-Provide tests that cover your changes and try to run the tests locally first.
-
-Automated Testing
-=================
-
-All pull requests and merges to 'develop' branch are tested in `Travis <https://travis-ci.org/>`_
-based on our `.travis.yml file <https://github.com/pypa/pip/blob/develop/.travis.yml>`_.
-
-Usually, a link to your specific travis build appears in pull requests, but if not,
-you can find it on our `travis pull requests page <https://travis-ci.org/pypa/pip/pull_requests>`_
-
-The only way to trigger Travis to run again for a pull request, is to submit another change to the pull branch.
-
-We also have Jenkins CI that runs regularly for certain python versions on windows and centos.
-
-Running tests
-=============
-
-OS Requirements: subversion, bazaar, git, and mercurial.
-
-Python Requirements: tox or pytest, virtualenv, scripttest, and mock
-
-Ways to run the tests locally:
-
-::
-
- $ tox -e py33           # The preferred way to run the tests, can use pyNN to
-                         # run for a particular version or leave off the -e to

- $ tox                   # Using tox against pip's tox.ini
-
-
-Getting Involved
-================
-
-The pip project welcomes help in the following ways:
-
-- Making Pull Requests for code, tests, or docs.
-- Commenting on open issues and pull requests.
-- Helping to answer questions on the mailing list.
-
-If you want to become an official maintainer, start by helping out.
-
-Later, when you think you're ready, get in touch with one of the maintainers,
-and they will initiate a vote.
-
-Release Process
-===============
-
-This process includes virtualenv, since pip releases necessitate a virtualenv release.
-
-As an example, the instructions assume we're releasing pip-1.4, and virtualenv-1.10.
-
-1. Upgrade setuptools, if needed:
-
- #. Upgrade setuptools in ``virtualenv/develop`` using the :ref:`Refresh virtualenv` process.
- #. Create a pull request against ``pip/develop`` with a modified ``.travis.yml`` file that installs virtualenv from ``virtualenv/develop``, to confirm the travis builds are still passing.
-
-2. Create Release branches:
-
- #. Create ``pip/release-1.4`` branch.
- #. In ``pip/develop``, change ``pip.version`` to '1.5.dev1'.
- #. Create ``virtualenv/release-1.10`` branch.
- #. In ``virtualenv/develop``, change ``virtualenv.version`` to '1.11.dev1'.
-
-3. Prepare "rcX":
-
- #. In ``pip/release-1.4``, change ``pip.version`` to '1.4rcX', and tag with '1.4rcX'.
- #. Build a pip sdist from ``pip/release-1.4``, and build it into ``virtualenv/release-1.10`` using the :ref:`Refresh virtualenv` process.
- #. In ``virtualenv/release-1.10``, change ``virtualenv.version`` to '1.10rcX', and tag with '1.10rcX'.
-
-4. Announce ``pip-1.4rcX`` and ``virtualenv-1.10rcX`` with the :ref:`RC Install Instructions` and elicit feedback.
-
-5. Apply fixes to 'rcX':
-
- #. Apply fixes to ``pip/release-1.4`` and ``virtualenv/release-1.10``
- #. Periodically merge fixes to ``pip/develop`` and ``virtualenv/develop``
-
-6. Repeat #4 thru #6 if needed.
-
-7. Final Release:
-
- #. In ``pip/release-1.4``, change ``pip.version`` to '1.4', and tag with '1.4'.
- #. Merge ``pip/release-1.4`` to ``pip/master``.
- #. Build a pip sdist from ``pip/release-1.4``, and load it into ``virtualenv/release-1.10`` using the :ref:`Refresh virtualenv` process.
- #. Merge ``vitualenv/release-1.10`` to ``virtualenv/develop``.
- #. In ``virtualenv/release-1.10``, change ``virtualenv.version`` to '1.10', and tag with '1.10'.
- #. Merge ``virtualenv/release-1.10`` to ``virtualenv/master``
- #. Build and upload pip and virtualenv sdists to PyPI.

-Python & OS Support
--------------------
-
-pip works with CPython versions 2.6, 2.7, 3.1, 3.2, 3.3, 3.4 and also pypy.
-
-pip works on Unix/Linux, OS X, and Windows.

-
-Install or Upgrade pip
-----------------------
-
-To install or upgrade pip, securely download `get-pip.py
-<https://raw.github.com/pypa/pip/master/contrib/get-pip.py>`_. [1]_
-
-Then run the following (which may require administrator access)::
-
- $ python get-pip.py
-
-.. note::
-
-    Beginning with v1.5.1, pip does not require `setuptools`_ prior to running
-    `get-pip.py`. Additionally, if `setuptools`_ (or `distribute`_) is not
-    already installed, `get-pip.py` will install `setuptools`_ for you.

-Internal Details
-================
-
-.. _`Requirements File Format`:
-
-Requirements File Format
-========================
-
-Each line of the requirements file indicates something to be installed,
-and like arguments to :ref:`pip install`, the following forms are supported::
-
-    <requirement specifier>
-    <archive url/path>
-    [-e] <local project path>
-    [-e] <vcs project url>
-
-See the :ref:`pip install Examples<pip install Examples>` for examples of all these forms.
-
-A line beginning with ``#`` is treated as a comment and ignored.
-
-Additionally, the following :ref:`Package Index Options <Package Index Options>` are supported
-
-  *  :ref:`-i, --index-url <--index-url>`
-  *  :ref:`--extra-index-url <--extra-index-url>`
-  *  :ref:`--no-index <--no-index>`
-  *  :ref:`-f, --find-links <--find-links>`
-  *  :ref:`--allow-external <--allow-external>`
-  *  :ref:`--allow-all-external <--allow-external>`
-  *  :ref:`--allow-unverified <--allow-unverified>`
-
-For example, to specify :ref:`--no-index <--no-index>` and 2 :ref:`--find-links <--find-links>` locations:
-
-::
-
---no-index
---find-links /my/local/archives
---find-links http://some.archives.com/archives
-
-
-Lastly, if you wish, you can refer to other requirements files, like this::
-
-    -r more_requirements.txt
-
-.. _`Requirement Specifiers`:
-
-Requirement Specifiers
-======================
-
-pip supports installing from "requirement specifiers" as implemented in
-`pkg_resources Requirements <http://packages.python.org/setuptools/pkg_resources.html#requirement-objects>`_
-
-Some Examples:
-
- ::
-
-  'FooProject >= 1.2'
-  Fizzy [foo, bar]
-  'PickyThing<1.6,>1.9,!=1.9.6,<2.0a0,==2.4c1'
-  SomethingWhoseVersionIDontCareAbout
-
-.. note::
-
-  Use single or double quotes around specifiers to avoid ``>`` and ``<`` being interpreted as shell redirects. e.g. ``pip install 'FooProject>=1.2'``.
-
-
-.. _`Logging`:
-
-Logging
-=======
-
-Console logging
-~~~~~~~~~~~~~~~
-
-pip offers :ref:`-v, --verbose <--verbose>` and :ref:`-q, --quiet <--quiet>`
-to control the console log level.  Each option can be used multiple times and
-used together. One ``-v`` increases the verbosity by one, whereas one ``-q`` decreases it by
-one.
-
-The series of log levels, in order, are as follows::
-
-  VERBOSE_DEBUG, DEBUG, INFO, NOTIFY, WARN, ERROR, FATAL
-
-``NOTIFY`` is the default level.
-
-A few examples on how the parameters work to affect the level:
-
-* specifying nothing results in ``NOTIFY``
-* ``-v`` results in ``INFO``
-* ``-vv`` results in ``DEBUG``
-* ``-q`` results in ``WARN``
-* ``-vq`` results in ``NOTIFY``
-
-The most practical use case for users is either ``-v`` or ``-vv`` to see
-additional logging to help troubleshoot an issue.
-
-
-.. _`FileLogging`:
-
-File logging
-~~~~~~~~~~~~
-
-pip offers the :ref:`--log <--log>` option for specifying a file where a maximum
-verbosity log will be kept.  This option is empty by default. This log appends
-to previous logging.
-
-Additionally, when commands fail (i.e. return a non-zero exit code), pip writes
-a "failure log" for the failed command. This log overwrites previous
-logging. The default location is as follows:
-
-* On Unix and Mac OS X: :file:`$HOME/.pip/pip.log`
-* On Windows, the configuration file is: :file:`%HOME%\\pip\\pip.log`
-
-The option for the failure log, is :ref:`--log-file <--log-file>`.
-
-Both logs add a line per execution to specify the date and what pip executable wrote the log.
-
-Like all pip options, ``--log`` and ``log-file``, can also be set as an environment
-variable, or placed into the pip config file.  See the :ref:`Configuration`
-section.
-
-
-.. _`Pre Release Versions`:
-
-Pre-release Versions
-====================
-
-Starting with v1.4, pip will only install stable versions as specified by `PEP426`_ by default. If
-a version cannot be parsed as a compliant `PEP426`_ version then it is assumed
-to be a pre-release.
-
-If a Requirement specifier includes a pre-release or development version (e.g. ``>=0.0.dev0``) then
-pip will allow pre-release and development versions for that requirement. This does not include
-the != flag.
-
-The ``pip install`` command also supports a :ref:`--pre <install_--pre>` flag that will enable
-installing pre-releases and development releases.
-
-
-.. _PEP426: http://www.python.org/dev/peps/pep-0426
-
-.. _`Externally Hosted Files`:
-
-Externally Hosted Files
-=======================
-
-Starting with v1.4, pip will warn about installing any file that does not come
-from the primary index. As of version 1.5, pip defaults to ignoring these files
-unless asked to consider them.
-
-The ``pip install`` command supports a
-:ref:`--allow-external PROJECT <--allow-external>` option that will enable
-installing links that are linked directly from the simple index but to an
-external host that also have a supported hash fragment. Externally hosted
-files for all projects may be enabled using the
-:ref:`--allow-all-external <--allow-all-external>` flag to the ``pip install``
-command.
-
-The ``pip install`` command also supports a
-:ref:`--allow-unverified PROJECT <--allow-unverified>` option that will enable
-installing insecurely linked files. These are either directly linked (as above)
-files without a hash, or files that are linked from either the home page or the
-download url of a package.
-
-These options can be used in a requirements file.  Assuming some fictional
-`ExternalPackage` that is hosted external and unverified, then your requirements
-file would be like so::
-
-    --allow-external ExternalPackage
-    --allow-unverified ExternalPackage
-    ExternalPackage
-
-
-.. _`VCS Support`:
-
-VCS Support
-===========
-
-pip supports installing from Git, Mercurial, Subversion and Bazaar, and detects the type of VCS using url prefixes: "git+", "hg+", "bzr+", "svn+".
-
-pip requires a working VCS command on your path: git, hg, svn, or bzr.
-
-VCS projects can be installed in :ref:`editable mode <editable-installs>` (using the :ref:`--editable <install_--editable>` option) or not.
-
-* For editable installs, the clone location by default is "<venv path>/src/SomeProject" in virtual environments, and "<cwd>/src/SomeProject" for global installs.
-  The :ref:`--src <install_--src>` option can be used to modify this location.
-* For non-editable installs, the project is built locally in a temp dir and then installed normally.
-
-The url suffix "egg=<project name>" is used by pip in it's dependency logic to identify the project prior to pip downloading and analyzing the metadata.
-
-Git
-~~~
-
-pip currently supports cloning over ``git``, ``git+https`` and ``git+ssh``:
-
-Here are the supported forms::
-
-    [-e] git+git://git.myproject.org/MyProject#egg=MyProject
-    [-e] git+https://git.myproject.org/MyProject#egg=MyProject
-    [-e] git+ssh://git.myproject.org/MyProject#egg=MyProject
-    -e git+git@git.myproject.org:MyProject#egg=MyProject
-
-Passing branch names, a commit hash or a tag name is possible like so::
-
-    [-e] git://git.myproject.org/MyProject.git@master#egg=MyProject
-    [-e] git://git.myproject.org/MyProject.git@v1.0#egg=MyProject
-    [-e] git://git.myproject.org/MyProject.git@da39a3ee5e6b4b0d3255bfef95601890afd80709#egg=MyProject
-
-Mercurial
-~~~~~~~~~
-
-The supported schemes are: ``hg+http``, ``hg+https``,
-``hg+static-http`` and ``hg+ssh``.
-
-Here are the supported forms::
-
-    [-e] hg+http://hg.myproject.org/MyProject#egg=MyProject
-    [-e] hg+https://hg.myproject.org/MyProject#egg=MyProject
-    [-e] hg+ssh://hg.myproject.org/MyProject#egg=MyProject
-
-You can also specify a revision number, a revision hash, a tag name or a local
-branch name like so::
-
-    [-e] hg+http://hg.myproject.org/MyProject@da39a3ee5e6b#egg=MyProject
-    [-e] hg+http://hg.myproject.org/MyProject@2019#egg=MyProject
-    [-e] hg+http://hg.myproject.org/MyProject@v1.0#egg=MyProject
-    [-e] hg+http://hg.myproject.org/MyProject@special_feature#egg=MyProject
-
-Subversion
-~~~~~~~~~~
-
-pip supports the URL schemes ``svn``, ``svn+svn``, ``svn+http``, ``svn+https``, ``svn+ssh``.
-
-You can also give specific revisions to an SVN URL, like so::
-
-    [-e] svn+svn://svn.myproject.org/svn/MyProject#egg=MyProject
-    [-e] svn+http://svn.myproject.org/svn/MyProject/trunk@2019#egg=MyProject
-
-which will check out revision 2019.  ``@{20080101}`` would also check
-out the revision from 2008-01-01. You can only check out specific
-revisions using ``-e svn+...``.
-
-Bazaar
-~~~~~~
-
-pip supports Bazaar using the ``bzr+http``, ``bzr+https``, ``bzr+ssh``,
-``bzr+sftp``, ``bzr+ftp`` and ``bzr+lp`` schemes.
-
-Here are the supported forms::
-
-    [-e] bzr+http://bzr.myproject.org/MyProject/trunk#egg=MyProject
-    [-e] bzr+sftp://user@myproject.org/MyProject/trunk#egg=MyProject
-    [-e] bzr+ssh://user@myproject.org/MyProject/trunk#egg=MyProject
-    [-e] bzr+ftp://user@myproject.org/MyProject/trunk#egg=MyProject
-    [-e] bzr+lp:MyProject#egg=MyProject
-
-Tags or revisions can be installed like so::
-
-    [-e] bzr+https://bzr.myproject.org/MyProject/trunk@2019#egg=MyProject
-    [-e] bzr+http://bzr.myproject.org/MyProject/trunk@v1.0#egg=MyProject

-Finding Packages
-================
-
-pip searches for packages on `PyPI <http://pypi.python.org>`_ using the
-`http simple interface <http://pypi.python.org/simple>`_,
-which is documented `here <http://packages.python.org/setuptools/easy_install.html#package-index-api>`_
-and `there <http://www.python.org/dev/peps/pep-0301/>`_
-
-pip offers a set of :ref:`Package Index Options <Package Index Options>` for modifying how packages are found.
-
-See the :ref:`pip install Examples<pip install Examples>`.
-
-
-.. _`SSL Certificate Verification`:
-
-SSL Certificate Verification
-============================
-
-Starting with v1.3, pip provides SSL certificate verification over https, for the purpose
-of providing secure, certified downloads from PyPI.
-
-
-Hash Verification
-=================
-
-PyPI provides md5 hashes in the hash fragment of package download urls.
-
-pip supports checking this, as well as any of the
-guaranteed hashlib algorithms (sha1, sha224, sha384, sha256, sha512, md5).
-
-The hash fragment is case sensitive (i.e. sha1 not SHA1).
-
-This check is only intended to provide basic download corruption protection.
-It is not intended to provide security against tampering. For that,
-see :ref:`SSL Certificate Verification`
-
-
-Download Cache
-==============
-
-pip offers a :ref:`--download-cache <install_--download-cache>` option for installs to prevent redundant downloads of archives from PyPI.
-
-The point of this cache is *not* to circumvent the index crawling process, but to *just* prevent redundant downloads.
-
-Items are stored in this cache based on the url the archive was found at, not simply the archive name.
-
-If you want a fast/local install solution that circumvents crawling PyPI, see the :ref:`Fast & Local Installs` Cookbook entry.
-
-Like all options, :ref:`--download-cache <install_--download-cache>`, can also be set as an environment variable, or placed into the pip config file.
-See the :ref:`Configuration` section.
-
-
-.. _`editable-installs`:
-
-"Editable" Installs
-===================
-
-"Editable" installs are fundamentally `"setuptools develop mode" <http://packages.python.org/setuptools/setuptools.html#development-mode>`_ installs.
-
-You can install local projects or VCS projects in "editable" mode::
-
-$ pip install -e path/to/SomeProject
-$ pip install -e git+http://repo/my_project.git#egg=SomeProject
-
-For local projects, the "SomeProject.egg-info" directory is created relative to the project path.
-This is one advantage over just using ``setup.py develop``, which creates the "egg-info" directly relative the current working directory.
-
-
-setuptools & pkg_resources
-==========================
-
-Internally, pip uses the `setuptools` package, and the `pkg_resources` module, which are available from the project, `Setuptools`_.
-
-Here are some examples of how pip uses `setuptools` and `pkg_resources`:
-
-* The core of pip's install process uses the `setuptools`'s "install" command.
-* Editable ("-e") installs use the `setuptools`'s "develop" command.
-* pip uses `pkg_resources` for version parsing, for detecting version conflicts, and to determine what projects are installed,
-

-virtualenv
-----------
-
-pip is most nutritious when used with `virtualenv
-<http://pypi.python.org/pypi/virtualenv>`__.  One of the reasons pip
-doesn't install "multi-version" eggs is that virtualenv removes much of the need
-for it.  Because pip is installed by virtualenv, just use
-``path/to/my/environment/bin/pip`` to install things into that
-specific environment.
-
-To tell pip to only run if there is a virtualenv currently activated,
-and to bail if not, use::
-
-    export PIP_REQUIRE_VIRTUALENV=true
-
-easy_install
-------------
-
-pip was originally written to improve on `easy_install <http://pythonhosted.org/setuptools/easy_install.html>`_ in the following ways:
-
-* 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.
-
-pip doesn't do everything that easy_install does. Specifically:
-
-* It cannot install from eggs.  That’s not a problem anymore though because pip
-  supports the superior binary `wheel format
-  <https://wheel.readthedocs.org/en/latest/>`_ since the 1.4 release.
-
-* It is incompatible with some packages that extensively customize distutils
-  or setuptools in their ``setup.py`` files.
-
-
-buildout
---------
-
-If you are using `zc.buildout
-<http://pypi.python.org/pypi/zc.buildout>`_ you should look at
-`gp.recipe.pip <http://pypi.python.org/pypi/gp.recipe.pip>`_ as an
-option to use pip and virtualenv in your buildouts.

-        quote_attr_values=True|False
-          Whether to quote attribute values that don't require quoting
-          per HTML5 parsing rules.
-        quote_char=u'"'|u"'"
-          Use given quote character for attribute quoting. Default is to
-          use double quote unless attribute value contains a double quote,
-          in which case single quotes are used instead.
-        escape_lt_in_attrs=False|True
-          Whether to escape < in attribute values.
-        escape_rcdata=False|True
-          Whether to escape characters that need to be escaped within normal
-          elements within rcdata elements such as style.
-        resolve_entities=True|False
-          Whether to resolve named character entities that appear in the

-          Places a space immediately before the closing slash in a tag
-          using a trailing solidus. E.g. <hr />. Requires use_trailing_solidus.
-        sanitize=False|True
-          Strip all unsafe or unknown constructs from output.
