+
+        An ISO-8601 datetime string consists of a date portion, followed
+        optionally by a time portion - the date and time portions are separated
+        by a single character separator, which is ``T`` in the official
+        standard. Incomplete date formats (such as ``YYYY-MM``) may *not* be
+        combined with a time portion.
+
+        Supported date formats are:
+
+        Common:
+
+        - ``YYYY``
+        - ``YYYY-MM`` or ``YYYYMM``
+        - ``YYYY-MM-DD`` or ``YYYYMMDD``
+
+        Uncommon:
+
+        - ``YYYY-Www`` or ``YYYYWww`` - ISO week (day defaults to 0)
+        - ``YYYY-Www-D`` or ``YYYYWwwD`` - ISO week and day
+
+        The ISO week and day numbering follows the same logic as
+        :func:`datetime.date.isocalendar`.
+
+        Supported time formats are:
+
+        - ``hh``
+        - ``hh:mm`` or ``hhmm``
+        - ``hh:mm:ss`` or ``hhmmss``
+        - ``hh:mm:ss.ssssss`` (Up to 6 sub-second digits)
+
+        Midnight is a special case for `hh`, as the standard supports both
+        00:00 and 24:00 as a representation. The decimal separator can be
+        either a dot or a comma.
+
+
+        .. caution::
+
+            Support for fractional components other than seconds is part of the
+            ISO-8601 standard, but is not currently implemented in this parser.
+
+        Supported time zone offset formats are:
+
+        - `Z` (UTC)
+        - `±HH:MM`
+        - `±HHMM`
+        - `±HH`
+
+        Offsets will be represented as :class:`dateutil.tz.tzoffset` objects,
+        with the exception of UTC, which will be represented as
+        :class:`dateutil.tz.tzutc`. Time zone offsets equivalent to UTC (such
+        as `+00:00`) will also be represented as :class:`dateutil.tz.tzutc`.

+    """
+    The relativedelta type is designed to be applied to an existing datetime and
+    can replace specific components of that datetime, or represents an interval
+    of time.
+
+    It is based on the specification of the excellent work done by M.-A. Lemburg
+    in his
+    `mx.DateTime <https://www.egenix.com/products/python/mxBase/mxDateTime/>`_ extension.
+    However, notice that this type does *NOT* implement the same algorithm as
+    his work. Do *NOT* expect it to behave like mx.DateTime's counterpart.
+
+    There are two different ways to build a relativedelta instance. The
+    first one is passing it two date/datetime classes::
+
+        relativedelta(datetime1, datetime2)
+
+    The second one is passing it any number of the following keyword arguments::
+
+        relativedelta(arg1=x,arg2=y,arg3=z...)
+
+        year, month, day, hour, minute, second, microsecond:
+            Absolute information (argument is singular); adding or subtracting a
+            relativedelta with absolute information does not perform an arithmetic
+            operation, but rather REPLACES the corresponding value in the
+            original datetime with the value(s) in relativedelta.
+
+        years, months, weeks, days, hours, minutes, seconds, microseconds:
+            Relative information, may be negative (argument is plural); adding
+            or subtracting a relativedelta with relative information performs
+            the corresponding arithmetic operation on the original datetime value
+            with the information in the relativedelta.
+
+        weekday: 
+            One of the weekday instances (MO, TU, etc) available in the
+            relativedelta module. These instances may receive a parameter N,
+            specifying the Nth weekday, which could be positive or negative
+            (like MO(+1) or MO(-2)). Not specifying it is the same as specifying
+            +1. You can also use an integer, where 0=MO. This argument is always
+            relative e.g. if the calculated date is already Monday, using MO(1)
+            or MO(-1) won't change the day. To effectively make it absolute, use
+            it in combination with the day argument (e.g. day=1, MO(1) for first
+            Monday of the month).
+
+        leapdays:
+            Will add given days to the date found, if year is a leap
+            year, and the date found is post 28 of february.
+
+        yearday, nlyearday:
+            Set the yearday or the non-leap year day (jump leap days).
+            These are converted to day/month/leapdays information.
+
+    There are relative and absolute forms of the keyword
+    arguments. The plural is relative, and the singular is
+    absolute. For each argument in the order below, the absolute form
+    is applied first (by setting each attribute to that value) and
+    then the relative form (by adding the value to the attribute).
+
+    The order of attributes considered when this relativedelta is
+    added to a datetime is:
+
+    1. Year
+    2. Month
+    3. Day
+    4. Hours
+    5. Minutes
+    6. Seconds
+    7. Microseconds
+
+    Finally, weekday is applied, using the rule described above.
+
+    For example
+
+    >>> from datetime import datetime
+    >>> from dateutil.relativedelta import relativedelta, MO
+    >>> dt = datetime(2018, 4, 9, 13, 37, 0)
+    >>> delta = relativedelta(hours=25, day=1, weekday=MO(1))
+    >>> dt + delta
+    datetime.datetime(2018, 4, 2, 14, 37)
+
+    First, the day is set to 1 (the first of the month), then 25 hours
+    are added, to get to the 2nd day and 14th hour, finally the
+    weekday is applied, but since the 2nd is already a Monday there is
+    no effect.

+
+The `dateutil` module provides powerful extensions to
+the standard `datetime` module, available in Python.
+
+Installation
+============
+`dateutil` can be installed from PyPI using `pip` (note that the package name is
+different from the importable name)::
+
+    pip install python-dateutil
+
+Download
+========
+dateutil is available on PyPI
+https://pypi.org/project/python-dateutil/
+
+The documentation is hosted at:
+https://dateutil.readthedocs.io/en/stable/
+
+Code
+====
+The code and issue tracker are hosted on GitHub:
+https://github.com/dateutil/dateutil/
+
+Features
+========
+
+* Computing of relative deltas (next month, next year,
+  next Monday, last week of month, etc);
+* Computing of relative deltas between two given
+  date and/or datetime objects;
+* Computing of dates based on very flexible recurrence rules,
+  using a superset of the `iCalendar <https://www.ietf.org/rfc/rfc2445.txt>`_
+  specification. Parsing of RFC strings is supported as well.
+* Generic parsing of dates in almost any string format;
+* Timezone (tzinfo) implementations for tzfile(5) format
+  files (/etc/localtime, /usr/share/zoneinfo, etc), TZ
+  environment string (in all known formats), iCalendar
+  format files, given ranges (with help from relative deltas),
+  local machine timezone, fixed offset timezone, UTC timezone,
+  and Windows registry-based time zones.
+* Internal up-to-date world timezone information based on
+  Olson's database.
+* Computing of Easter Sunday dates for any given year,
+  using Western, Orthodox or Julian algorithms;
+* A comprehensive test suite.
+
+Quick example
+=============
+Here's a snapshot, just to give an idea about the power of the
+package. For more examples, look at the documentation.
+
+Suppose you want to know how much time is left, in
+years/months/days/etc, before the next easter happening on a
+year with a Friday 13th in August, and you want to get today's
+date out of the "date" unix system command. Here is the code:
+
+.. code-block:: python3
+
+    >>> from dateutil.relativedelta import *
+    >>> from dateutil.easter import *
+    >>> from dateutil.rrule import *
+    >>> from dateutil.parser import *
+    >>> from datetime import *
+    >>> now = parse("Sat Oct 11 17:13:46 UTC 2003")
+    >>> today = now.date()
+    >>> year = rrule(YEARLY,dtstart=now,bymonth=8,bymonthday=13,byweekday=FR)[0].year
+    >>> rdelta = relativedelta(easter(year), today)
+    >>> print("Today is: %s" % today)
+    Today is: 2003-10-11
+    >>> print("Year with next Aug 13th on a Friday is: %s" % year)
+    Year with next Aug 13th on a Friday is: 2004
+    >>> print("How far is the Easter of that year: %s" % rdelta)
+    How far is the Easter of that year: relativedelta(months=+6)
+    >>> print("And the Easter of that year is: %s" % (today+rdelta))
+    And the Easter of that year is: 2004-04-11
+
+Being exactly 6 months ahead was **really** a coincidence :)
+

+Description: Python Decouple: Strict separation of settings from code
+        ========================================================
+        
+        *Decouple* helps you to organize your settings so that you can
+        change parameters without having to redeploy your app.
+        
+        It also makes it easy for you to:
+        
+        #. store parameters in *ini* or *.env* files;
+        #. define comprehensive default values;
+        #. properly convert values to the correct data type;
+        #. have **only one** configuration module to rule all your instances.
+        
+        It was originally designed for Django, but became an independent generic tool
+        for separating settings from code.

+        .. contents:: Summary
+        
+        
+        Why?
+        ====
+        
+        Web framework's settings stores many different kinds of parameters:
+        
+        * Locale and i18n;
+        * Middlewares and Installed Apps;
+        * Resource handles to the database, Memcached, and other backing services;
+        * Credentials to external services such as Amazon S3 or Twitter;
+        * Per-deploy values such as the canonical hostname for the instance.
+        
+        The first 2 are *project settings* the last 3 are *instance settings*.
+        
+        You should be able to change *instance settings* without redeploying your app.
+        
+        Why not just use environment variables?
+        ---------------------------------------
+        
+        *Envvars* works, but since ``os.environ`` only returns strings, it's tricky.
+        
+        Let's say you have an *envvar* ``DEBUG=False``. If you run:
+        
+        .. code-block:: python
+        
+            if os.environ['DEBUG']:
+                print True
+            else:
+                print False
+        
+        It will print **True**, because ``os.environ['DEBUG']`` returns the **string** ``"False"``.
+        Since it's a non-empty string, it will be evaluated as True.
+        
+        *Decouple* provides a solution that doesn't look like a workaround: ``config('DEBUG', cast=bool)``.
+        
+        Usage
+        =====
+        
+        Install:
+        
+        .. code-block:: console
+        
+            pip install python-decouple
+        
+        
+        Then use it on your ``settings.py``.
+        
+        #. Import the ``config`` object:
+        
+           .. code-block:: python
+        
+             from decouple import config
+        
+        #. Retrieve the configuration parameters:
+        
+           .. code-block:: python
+        
+             SECRET_KEY = config('SECRET_KEY')
+             DEBUG = config('DEBUG', default=False, cast=bool)
+             EMAIL_HOST = config('EMAIL_HOST', default='localhost')
+             EMAIL_PORT = config('EMAIL_PORT', default=25, cast=int)
+        
+        Encodings
+        ---------
+        Decouple's default encoding is `UTF-8`.
+        
+        But you can specify your preferred encoding.
+        
+        Since `config` is lazy and only opens the configuration file when it's first needed, you have the chance to change
+        it's encoding right after import.
+        
+        .. code-block:: python
+        
+            from decouple import config
+            config.encoding = 'cp1251'
+            SECRET_KEY = config('SECRET_KEY')
+        
+        If you wish to fallback to your system's default encoding do:
+        
+        .. code-block:: python
+        
+            import locale
+            from decouple import config
+            config.encoding = locale.getpreferredencoding(False)
+            SECRET_KEY = config('SECRET_KEY')
+        
+        Where the settings data are stored?
+        -----------------------------------
+        
+        *Decouple* supports both *.ini* and *.env* files.
+        
+        Ini file
+        ~~~~~~~~
+        
+        Simply create a ``settings.ini`` next to your configuration module in the form:
+        
+        .. code-block:: ini
+        
+            [settings]
+            DEBUG=True
+            TEMPLATE_DEBUG=%(DEBUG)s
+            SECRET_KEY=ARANDOMSECRETKEY
+            DATABASE_URL=mysql://myuser:mypassword@myhost/mydatabase
+            PERCENTILE=90%%
+            #COMMENTED=42
+        
+        *Note*: Since ``ConfigParser`` supports *string interpolation*, to represent the character ``%`` you need to escape it as ``%%``.
+        
+        Env file
+        ~~~~~~~~
+        
+        Simply create a ``.env`` text file on your repository's root directory in the form:
+        
+        .. code-block:: console
+        
+            DEBUG=True
+            TEMPLATE_DEBUG=True
+            SECRET_KEY=ARANDOMSECRETKEY
+            DATABASE_URL=mysql://myuser:mypassword@myhost/mydatabase
+            PERCENTILE=90%
+            #COMMENTED=42
+        
+        Example: How do I use it with Django?
+        -------------------------------------
+        
+        Given that I have a ``.env`` file at my repository root directory, here is a snippet of my ``settings.py``.
+        
+        I also recommend using `pathlib <https://docs.python.org/3/library/pathlib.html>`_
+        and `dj-database-url <https://pypi.python.org/pypi/dj-database-url/>`_.
+        
+        .. code-block:: python
+        
+            # coding: utf-8
+            from decouple import config
+            from unipath import Path
+            from dj_database_url import parse as db_url
+        
+        
+            BASE_DIR = Path(__file__).parent
+        
+            DEBUG = config('DEBUG', default=False, cast=bool)
+            TEMPLATE_DEBUG = DEBUG
+        
+            DATABASES = {
+                'default': config(
+                    'DATABASE_URL',
+                    default='sqlite:///' + BASE_DIR.child('db.sqlite3'),
+                    cast=db_url
+                )
+            }
+        
+            TIME_ZONE = 'America/Sao_Paulo'
+            USE_L10N = True
+            USE_TZ = True
+        
+            SECRET_KEY = config('SECRET_KEY')
+        
+            EMAIL_HOST = config('EMAIL_HOST', default='localhost')
+            EMAIL_PORT = config('EMAIL_PORT', default=25, cast=int)
+            EMAIL_HOST_PASSWORD = config('EMAIL_HOST_PASSWORD', default='')
+            EMAIL_HOST_USER = config('EMAIL_HOST_USER', default='')
+            EMAIL_USE_TLS = config('EMAIL_USE_TLS', default=False, cast=bool)
+        
+            # ...
+        
+        Attention with *undefined* parameters
+        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+        
+        On the above example, all configuration parameters except ``SECRET_KEY = config('SECRET_KEY')``
+        have a default value to fallback if it does not exist on the ``.env`` file.
+        
+        If ``SECRET_KEY`` is not present in the ``.env``, *decouple* will raise an ``UndefinedValueError``.
+        
+        This *fail fast* policy helps you avoid chasing misbehaviors when you eventually forget a parameter.
+        
+        Overriding config files with environment variables
+        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+        
+        Sometimes you may want to change a parameter value without having to edit the ``.ini`` or ``.env`` files.
+        
+        Since version 3.0, *decouple* respects the *unix way*.
+        Therefore environment variables have precedence over config files.
+        
+        To override a config parameter you can simply do:
+        
+        .. code-block:: console
+        
+            DEBUG=True python manage.py
+        
+        
+        How it works?
+        =============
+        
+        *Decouple* always searches for *Options* in this order:
+        
+        #. Environment variables;
+        #. Repository: ini or .env file;
+        #. default argument passed to config.
+        
+        There are 4 classes doing the magic:
+        
+        
+        - ``Config``
+        
+            Coordinates all the configuration retrieval.
+        
+        - ``RepositoryIni``
+        
+            Can read values from ``os.environ`` and ini files, in that order.
+        
+            **Note:** Since version 3.0 *decouple* respects unix precedence of environment variables *over* config files.
+        
+        - ``RepositoryEnv``
+        
+            Can read values from ``os.environ`` and ``.env`` files.
+        
+            **Note:** Since version 3.0 *decouple* respects unix precedence of environment variables *over* config files.
+        
+        - ``AutoConfig``
+        
+            This is a *lazy* ``Config`` factory that detects which configuration repository you're using.
+        
+            It recursively searches up your configuration module path looking for a
+            ``settings.ini`` or a ``.env`` file.
+        
+            Optionally, it accepts ``search_path`` argument to explicitly define
+            where the search starts.
+        
+        The **config** object is an instance of ``AutoConfig`` that instantiates a ``Config`` with the proper ``Repository``
+        on the first time it is used.
+        
+        
+        Understanding the CAST argument
+        -------------------------------
+        
+        By default, all values returned by ``decouple`` are ``strings``, after all they are
+        read from ``text files`` or the ``envvars``.
+        
+        However, your Python code may expect some other value type, for example:
+        
+        * Django's ``DEBUG`` expects a boolean ``True`` or ``False``.
+        * Django's ``EMAIL_PORT`` expects an ``integer``.
+        * Django's ``ALLOWED_HOSTS`` expects a ``list`` of hostnames.
+        * Django's ``SECURE_PROXY_SSL_HEADER`` expects a ``tuple`` with two elements, the name of the header to look for and the required value.
+        
+        To meet this need, the ``config`` function accepts a ``cast`` argument which
+        receives any *callable*, that will be used to *transform* the string value
+        into something else.
+        
+        Let's see some examples for the above mentioned cases:
+        
+        .. code-block:: python
+        
+            >>> os.environ['DEBUG'] = 'False'
+            >>> config('DEBUG', cast=bool)
+            False
+        
+            >>> os.environ['EMAIL_PORT'] = '42'
+            >>> config('EMAIL_PORT', cast=int)
+            42
+        
+            >>> os.environ['ALLOWED_HOSTS'] = '.localhost, .herokuapp.com'
+            >>> config('ALLOWED_HOSTS', cast=lambda v: [s.strip() for s in v.split(',')])
+            ['.localhost', '.herokuapp.com']
+        
+            >>> os.environ['SECURE_PROXY_SSL_HEADER'] = 'HTTP_X_FORWARDED_PROTO, https'
+            >>> config('SECURE_PROXY_SSL_HEADER', cast=Csv(post_process=tuple))
+            ('HTTP_X_FORWARDED_PROTO', 'https')
+        
+        As you can see, ``cast`` is very flexible. But the last example got a bit complex.
+        
+        Built in Csv Helper
+        ~~~~~~~~~~~~~~~~~~~
+        
+        To address the complexity of the last example, *Decouple* comes with an extensible *Csv helper*.
+        
+        Let's improve the last example:
+        
+        .. code-block:: python
+        
+            >>> from decouple import Csv
+            >>> os.environ['ALLOWED_HOSTS'] = '.localhost, .herokuapp.com'
+            >>> config('ALLOWED_HOSTS', cast=Csv())
+            ['.localhost', '.herokuapp.com']
+        
+        You can also have a `default` value that must be a string to be processed by `Csv`.
+        
+        .. code-block:: python
+        
+            >>> from decouple import Csv
+            >>> config('ALLOWED_HOSTS', default='127.0.0.1', cast=Csv())
+            ['127.0.0.1']
+        
+        You can also parametrize the *Csv Helper* to return other types of data.
+        
+        .. code-block:: python
+        
+            >>> os.environ['LIST_OF_INTEGERS'] = '1,2,3,4,5'
+            >>> config('LIST_OF_INTEGERS', cast=Csv(int))
+            [1, 2, 3, 4, 5]
+        
+            >>> os.environ['COMPLEX_STRING'] = '%virtual_env%\t *important stuff*\t   trailing spaces   '
+            >>> csv = Csv(cast=lambda s: s.upper(), delimiter='\t', strip=' %*')
+            >>> csv(os.environ['COMPLEX_STRING'])
+            ['VIRTUAL_ENV', 'IMPORTANT STUFF', 'TRAILING SPACES']
+        
+        By default *Csv* returns a ``list``, but you can get a ``tuple`` or whatever you want using the ``post_process`` argument:
+        
+        .. code-block:: python
+        
+            >>> os.environ['SECURE_PROXY_SSL_HEADER'] = 'HTTP_X_FORWARDED_PROTO, https'
+            >>> config('SECURE_PROXY_SSL_HEADER', cast=Csv(post_process=tuple))
+            ('HTTP_X_FORWARDED_PROTO', 'https')
+

+===============================================================================
+
+Reads the key-value pair from `.env` file and adds them to environment
+variable. It is great for managing app settings during development and
+in production using [12-factor](http://12factor.net/) principles.
+
+> Do one thing, do it well!
+
+## Usages
+
+The easiest and most common usage consists on calling `load_dotenv` when
+the application starts, which will load environment variables from a
+file named `.env` in the current directory or any of its parents or from
+the path specificied; after that, you can just call the
+environment-related method you need as provided by `os.getenv`.
+
+`.env` looks like this:
+
+```shell
+# a comment that will be ignored.
+REDIS_ADDRESS=localhost:6379
+MEANING_OF_LIFE=42
+MULTILINE_VAR="hello\nworld"
+```
+
+You can optionally prefix each line with the word `export`, which is totally ignored by this library, but might allow you to [`source`](https://bash.cyberciti.biz/guide/Source_command) the file in bash.
+
+```
+export S3_BUCKET=YOURS3BUCKET
+export SECRET_KEY=YOURSECRETKEYGOESHERE
+```
+
+Python-dotenv can interpolate variables using POSIX variable expansion.
+
+The value of a variable is the first of the values defined in the following list:
+
+- Value of that variable in the environment.
+- Value of that variable in the `.env` file.
+- Default value, if provided.
+- Empty string.
+
+Ensure that variables are surrounded with `{}` like `${HOME}` as bare 
+variables such as `$HOME` are not expanded.
+
+```shell
+CONFIG_PATH=${HOME}/.config/foo
+DOMAIN=example.org
+EMAIL=admin@${DOMAIN}
+DEBUG=${DEBUG:-false}
+```
+
+## Getting started
+
+Install the latest version with:
+
+```shell
+pip install -U python-dotenv
+```
+
+Assuming you have created the `.env` file along-side your settings
+module.
+
+    .
+    ├── .env
+    └── settings.py
+
+Add the following code to your `settings.py`:
+
+```python
+# settings.py
+from dotenv import load_dotenv
+load_dotenv()
+
+# OR, the same with increased verbosity
+load_dotenv(verbose=True)
+
+# OR, explicitly providing path to '.env'
+from pathlib import Path  # python3 only
+env_path = Path('.') / '.env'
+load_dotenv(dotenv_path=env_path)
+```
+
+At this point, parsed key/value from the `.env` file is now present as
+system environment variable and they can be conveniently accessed via
+`os.getenv()`:
+
+```python
+# settings.py
+import os
+SECRET_KEY = os.getenv("EMAIL")
+DATABASE_PASSWORD = os.getenv("DATABASE_PASSWORD")
+```
+
+`load_dotenv` does not override existing System environment variables. To
+override, pass `override=True` to `load_dotenv()`.
+
+`load_dotenv` also accepts `encoding` parameter to open the `.env` file. The default encoding is platform dependent (whatever `locale.getpreferredencoding()` returns), but any encoding supported by Python can be used. See the [codecs](https://docs.python.org/3/library/codecs.html#standard-encodings) module for the list of supported encodings.
+
+You can use `find_dotenv()` method that will try to find a `.env` file
+by (a) guessing where to start using `__file__` or the working directory
+-- allowing this to work in non-file contexts such as IPython notebooks
+and the REPL, and then (b) walking up the directory tree looking for the
+specified file -- called `.env` by default.
+
+```python
+from dotenv import load_dotenv, find_dotenv
+load_dotenv(find_dotenv())
+```
+
+### In-memory filelikes
+
+It is possible to not rely on the filesystem to parse filelikes from
+other sources (e.g. from a network storage). `load_dotenv` and
+`dotenv_values` accepts a filelike `stream`. Just be sure to rewind it
+before passing.
+
+```python
+>>> from io import StringIO     # Python2: from StringIO import StringIO
+>>> from dotenv import dotenv_values
+>>> filelike = StringIO('SPAM=EGGS\n')
+>>> filelike.seek(0)
+>>> parsed = dotenv_values(stream=filelike)
+>>> parsed['SPAM']
+'EGGS'
+```
+
+The returned value is dictionary with key-value pairs.
+
+`dotenv_values` could be useful if you need to *consume* the envfile but
+not *apply* it directly into the system environment.
+
+### Django
+
+If you are using Django, you should add the above loader script at the
+top of `wsgi.py` and `manage.py`.
+
+
+## IPython Support
+
+You can use dotenv with IPython. You can either let the dotenv search
+for `.env` with `%dotenv` or provide the path to the `.env` file explicitly; see
+below for usages.
+
+    %load_ext dotenv
+
+    # Use find_dotenv to locate the file
+    %dotenv
+
+    # Specify a particular file
+    %dotenv relative/or/absolute/path/to/.env
+
+    # Use '-o' to indicate override of existing variables
+    %dotenv -o
+
+    # Use '-v' to turn verbose mode on
+    %dotenv -v
+
+
+## Command-line Interface
+
+For command-line support, use the CLI option during installation:
+
+```shell
+pip install -U "python-dotenv[cli]"
+```
+
+A CLI interface `dotenv` is also included, which helps you manipulate
+the `.env` file without manually opening it. The same CLI installed on
+remote machine combined with fabric (discussed later) will enable you to
+update your settings on a remote server; handy, isn't it!
+
+```
+Usage: dotenv [OPTIONS] COMMAND [ARGS]...
+
+  This script is used to set, get or unset values from a .env file.
+
+Options:
+  -f, --file PATH                 Location of the .env file, defaults to .env
+                                  file in current working directory.
+  -q, --quote [always|never|auto]
+                                  Whether to quote or not the variable values.
+                                  Default mode is always. This does not affect
+                                  parsing.
+  --help                          Show this message and exit.
+
+Commands:
+  get    Retrive the value for the given key.
+  list   Display all the stored key/value.
+  run    Run command with environment variables from .env file present
+  set    Store the given key/value.
+  unset  Removes the given key.
+```
+
+
+### Setting config on Remote Servers
+
+We make use of excellent [Fabric](http://www.fabfile.org/) to accomplish
+this. Add a config task to your local fabfile; `dotenv_path` is the
+location of the absolute path of `.env` file on the remote server.
+
+```python
+# fabfile.py
+
+import dotenv
+from fabric.api import task, run, env
+
+# absolute path to the location of .env on remote server.
+env.dotenv_path = '/opt/myapp/.env'
+
+@task
+def config(action=None, key=None, value=None):
+    '''Manage project configuration via .env
+
+    e.g: fab config:set,<key>,<value>
+         fab config:get,<key>
+         fab config:unset,<key>
+         fab config:list
+    '''
+    run('touch %(dotenv_path)s' % env)
+    command = dotenv.get_cli_string(env.dotenv_path, action, key, value)
+    run(command)
+```
+
+Usage is designed to mirror the Heroku config API very closely.
+
+Get all your remote config info with `fab config`:
+
+    $ fab config
+    foo="bar"
+
+Set remote config variables with `fab config:set,<key>,<value>`:
+
+    $ fab config:set,hello,world
+
+Get a single remote config variables with `fab config:get,<key>`:
+
+    $ fab config:get,hello
+
+Delete a remote config variables with `fab config:unset,<key>`:
+
+    $ fab config:unset,hello
+
+Thanks entirely to fabric and not one bit to this project, you can chain
+commands like so:
+`fab config:set,<key1>,<value1> config:set,<key2>,<value2>`
+
+    $ fab config:set,hello,world config:set,foo,bar config:set,fizz=buzz
