+# Heroku Buildpack: Python
+
+[![Build Status](https://travis-ci.org/heroku/heroku-buildpack-python.svg?branch=master)](https://travis-ci.org/heroku/heroku-buildpack-python)
+
+This is the official [Heroku buildpack](https://devcenter.heroku.com/articles/buildpacks) for Python apps, powered by [pip](https://pip.pypa.io/) and other excellent software.
+
+Recommended web frameworks include **Django** and **Flask**. The recommended webserver is **Gunicorn**. There are no restrictions around what software can be used (as long as it's pip-installable). Web processes must bind to `$PORT`, and only the HTTP protocol is permitted for incoming connections.
+
+Some Python packages with obscure C dependencies (e.g. scipy) are [not compatible](https://devcenter.heroku.com/articles/python-c-deps). 
+
+See it in Action
+----------------
+
+Deploying a Python application couldn't be easier:
+
+    $ ls
+    Procfile  requirements.txt  web.py
+
+    $ heroku create --buildpack heroku/python
+
+    $ git push heroku master
+    ...
+    -----> Python app detected
+    -----> Installing python-2.7.13

+           Installing collected packages: requests
+           Successfully installed requests-2.12.4
+           
+    -----> Discovering process types
+           Procfile declares types -> (none)
+
+A `requirements.txt` file must be present at the root of your application's repository.
+
+You can also specify the latest production release of this buildpack for upcoming builds of an existing application:
+
+    $ heroku buildpacks:set heroku/python
+
+
+Specify a Python Runtime
+------------------------
+
+Specific versions of the Python runtime can be specified with a `runtime.txt` file:
+
+    $ cat runtime.txt
+    python-3.6.0
+
+Runtime options include:
+
+- `python-2.7.13`
+- `python-3.6.0`
+- `pypy-5.6.0` (unsupported, experimental)
+- `pypy3-5.5.0` (unsupported, experimental)

-You can also add it to upcoming builds of an existing application:
-
-    $ heroku config:add BUILDPACK_URL=git://github.com/heroku/heroku-buildpack-python.git
-
-The buildpack will detect your app as Python if it has the file `requirements.txt` in the root. 
-
-It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug. 
-
-Specify a Runtime
-----------------
-
-You can also provide arbitrary releases Python with a `runtime.txt` file.
-
-    $ cat runtime.txt
-    python-3.3.0
-

- python-2.7.4
- python-3.3.1

+# 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 :)

+Maya: Datetime for Humans™
+==========================
+
+.. image:: https://img.shields.io/pypi/v/maya.svg
+    :target: https://pypi.python.org/pypi/maya
+
+.. image:: https://travis-ci.org/kennethreitz/maya.svg?branch=master

+
+.. image:: https://img.shields.io/badge/SayThanks.io-☼-1EAEDB.svg
+    :target: https://saythanks.io/to/kennethreitz
+
+
+Datetimes are very frustrating to work with in Python, especially when dealing
+with different locales on different systems. This library exists to make the
+simple things **much** easier, while admitting that time is an illusion
+(timezones doubly so).
+
+Datetimes should be interacted with via an API written for humans.
+
+Maya is mostly built around the headaches and use-cases around parsing datetime data from websites.
+
+
+☤ Basic Usage of Maya
+---------------------
+
+Behold, datetimes for humans!
+
+.. code-block:: pycon
+
+    >>> now = maya.now()
+    <MayaDT epoch=1481850660.9>
+
+    >>> tomorrow = maya.when('tomorrow')
+    <MayaDT epoch=1481919067.23>
+
+    >>> tomorrow.slang_date()
+    'tomorrow'
+
+    >>> tomorrow.slang_time()
+    '23 hours from now'
+
+    >>> tomorrow.iso8601()
+    '2016-12-16T15:11:30.263350Z'
+
+    >>> tomorrow.rfc2822()
+    'Fri, 16 Dec 2016 20:11:30 -0000'
+
+    >>> tomorrow.datetime()
+    datetime.datetime(2016, 12, 16, 15, 11, 30, 263350, tzinfo=<UTC>)
+
+    # Automatically parse datetime strings and generate naive datetimes.
+    >>> scraped = '2016-12-16 18:23:45.423992+00:00'
+    >>> maya.parse(scraped).datetime(to_timezone='US/Eastern', naive=True)
+    datetime.datetime(2016, 12, 16, 13, 23, 45, 423992)
+
+    >>> rand_day = maya.when('2011-02-07', timezone='US/Eastern')
+    <MayaDT epoch=1297036800.0>
+
+    # Note how this is the 6th, not the 7th.
+    >>> rand_day.day
+    6
+
+    # Always.
+    >>> rand_day.timezone
+    UTC
+
+☤ Why is this useful?
+---------------------
+
+- All timezone algebra will behave identically on all machines, regardless of system locale.
+- Complete symmetric import and export of both ISO 8601 and RFC 2822 datetime stamps.
+- Fantastic parsing of both dates written for/by humans and machines (``maya.when()`` vs ``maya.parse()``).
+- Support for human slang, both import and export (e.g. `an hour ago`).
+- Datetimes can very easily be generated, with or without tzinfo attached.
+- This library is based around epoch time, but dates before Jan 1 1970 are indeed supported, via negative integers.
+- Maya never panics, and always carries a towel.
+
+
+☤ What about Delorean, Arrow, & Pendulum?
+-----------------------------------------
+
+Arrow, for example, is a fantastic library, but isn't what I wanted in a datetime library. In many ways, it's better than Maya for certain things. In some ways, in my opinion, it's not.
+
+I simply desire a sane API for datetimes that made sense to me for all the things I'd ever want to do—especially when dealing with timezone algebra. Arrow doesn't do all of the things I need (but it does a lot more!). Maya does do exactly what I need.
+
+I think these projects complement each-other, personally. Maya is great for parsing websites. For example- Arrow supports floors and ceilings and spans of dates, which Maya does not at all.
+
+
+☤ Installing Maya
+-----------------
+
+Installation is easy, with pip::
+
+    $ pip install maya
+
