License

THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.

BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND CONDITIONS.

1. Definitions

"Adaptation" means a work based upon the Work, or upon the Work and other pre-existing works, such as a translation, adaptation, derivative work, arrangement of music or other alterations of a literary or artistic work, or phonogram or performance and includes cinematographic adaptations or any other form in which the Work may be recast, transformed, or adapted including in any form recognizably derived from the original, except that a work that constitutes a Collection will not be considered an Adaptation for the purpose of this License. For the avoidance of doubt, where the Work is a musical work, performance or phonogram, the synchronization of the Work in timed-relation with a moving image ("synching") will be considered an Adaptation for the purpose of this License.
"Collection" means a collection of literary or artistic works, such as encyclopedias and anthologies, or performances, phonograms or broadcasts, or other works or subject matter other than works listed in Section 1(f) below, which, by reason of the selection and arrangement of their contents, constitute intellectual creations, in which the Work is included in its entirety in unmodified form along with one or more other contributions, each constituting separate and independent works in themselves, which together are assembled into a collective whole. A work that constitutes a Collection will not be considered an Adaptation (as defined below) for the purposes of this License.
"Creative Commons Compatible License" means a license that is listed at http://creativecommons.org/compatiblelicenses that has been approved by Creative Commons as being essentially equivalent to this License, including, at a minimum, because that license: (i) contains terms that have the same purpose, meaning and effect as the License Elements of this License; and, (ii) explicitly permits the relicensing of adaptations of works made available under that license under this License or a Creative Commons jurisdiction license with the same License Elements as this License.
"Distribute" means to make available to the public the original and copies of the Work or Adaptation, as appropriate, through sale or other transfer of ownership.

"Licensor" means the individual, individuals, entity or entities that offer(s) the Work under the terms of this License.
"Original Author" means, in the case of a literary or artistic work, the individual, individuals, entity or entities who created the Work or if no individual or entity can be identified, the publisher; and in addition (i) in the case of a performance the actors, singers, musicians, dancers, and other persons who act, sing, deliver, declaim, play in, interpret or otherwise perform literary or artistic works or expressions of folklore; (ii) in the case of a phonogram the producer being the person or legal entity who first fixes the sounds of a performance or other sounds; and, (iii) in the case of broadcasts, the organization that transmits the broadcast.
"Work" means the literary and/or artistic work offered under the terms of this License including without limitation any production in the literary, scientific and artistic domain, whatever may be the mode or form of its expression including digital form, such as a book, pamphlet and other writing; a lecture, address, sermon or other work of the same nature; a dramatic or dramatico-musical work; a choreographic work or entertainment in dumb show; a musical composition with or without words; a cinematographic work to which are assimilated works expressed by a process analogous to cinematography; a work of drawing, painting, architecture, sculpture, engraving or lithography; a photographic work to which are assimilated works expressed by a process analogous to photography; a work of applied art; an illustration, map, plan, sketch or three-dimensional work relative to geography, topography, architecture or science; a performance; a broadcast; a phonogram; a compilation of data to the extent it is protected as a copyrightable work; or a work performed by a variety or circus performer to the extent it is not otherwise considered a literary or artistic work.
"You" means an individual or entity exercising rights under this License who has not previously violated the terms of this License with respect to the Work, or who has received express permission from the Licensor to exercise rights under this License despite a previous violation.
"Publicly Perform" means to perform public recitations of the Work and to communicate to the public those public recitations, by any means or process, including by wire or wireless means or public digital performances; to make available to the public Works in such a way that members of the public may access these Works from a place and at a place individually chosen by them; to perform the Work to the public by any means or process and the communication to the public of the performances of the Work, including by public digital performance; to broadcast and rebroadcast the Work by any means including signs, sounds or images.
"Reproduce" means to make copies of the Work by any means including without limitation by sound or visual recordings and the right of fixation and reproducing fixations of the Work, including storage of a protected performance or phonogram in digital form or other electronic medium.
2. Fair Dealing Rights. Nothing in this License is intended to reduce, limit, or restrict any uses free from copyright or rights arising from limitations or exceptions that are provided for in connection with the copyright protection under copyright law or other applicable laws.

3. License Grant. Subject to the terms and conditions of this License, Licensor hereby grants You a worldwide, royalty-free, non-exclusive, perpetual (for the duration of the applicable copyright) license to exercise the rights in the Work as stated below:

to Reproduce the Work, to incorporate the Work into one or more Collections, and to Reproduce the Work as incorporated in the Collections;
to create and Reproduce Adaptations provided that any such Adaptation, including any translation in any medium, takes reasonable steps to clearly label, demarcate or otherwise identify that changes were made to the original Work. For example, a translation could be marked "The original work was translated from English to Spanish," or a modification could indicate "The original work has been modified.";
to Distribute and Publicly Perform the Work including as incorporated in Collections; and,
to Distribute and Publicly Perform Adaptations.
For the avoidance of doubt:

Non-waivable Compulsory License Schemes. In those jurisdictions in which the right to collect royalties through any statutory or compulsory licensing scheme cannot be waived, the Licensor reserves the exclusive right to collect such royalties for any exercise by You of the rights granted under this License;
Waivable Compulsory License Schemes. In those jurisdictions in which the right to collect royalties through any statutory or compulsory licensing scheme can be waived, the Licensor waives the exclusive right to collect such royalties for any exercise by You of the rights granted under this License; and,
Voluntary License Schemes. The Licensor waives the right to collect royalties, whether individually or, in the event that the Licensor is a member of a collecting society that administers voluntary licensing schemes, via that society, from any exercise by You of the rights granted under this License.
The above rights may be exercised in all media and formats whether now known or hereafter devised. The above rights include the right to make such modifications as are technically necessary to exercise the rights in other media and formats. Subject to Section 8(f), all rights not expressly granted by Licensor are hereby reserved.

4. Restrictions. The license granted in Section 3 above is expressly made subject to and limited by the following restrictions:

You may Distribute or Publicly Perform the Work only under the terms of this License. You must include a copy of, or the Uniform Resource Identifier (URI) for, this License with every copy of the Work You Distribute or Publicly Perform. You may not offer or impose any terms on the Work that restrict the terms of this License or the ability of the recipient of the Work to exercise the rights granted to that recipient under the terms of the License. You may not sublicense the Work. You must keep intact all notices that refer to this License and to the disclaimer of warranties with every copy of the Work You Distribute or Publicly Perform. When You Distribute or Publicly Perform the Work, You may not impose any effective technological measures on the Work that restrict the ability of a recipient of the Work from You to exercise the rights granted to that recipient under the terms of the License. This Section 4(a) applies to the Work as incorporated in a Collection, but this does not require the Collection apart from the Work itself to be made subject to the terms of this License. If You create a Collection, upon notice from any Licensor You must, to the extent practicable, remove from the Collection any credit as required by Section 4(c), as requested. If You create an Adaptation, upon notice from any Licensor You must, to the extent practicable, remove from the Adaptation any credit as required by Section 4(c), as requested.
You may Distribute or Publicly Perform an Adaptation only under the terms of: (i) this License; (ii) a later version of this License with the same License Elements as this License; (iii) a Creative Commons jurisdiction license (either this or a later license version) that contains the same License Elements as this License (e.g., Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible License. If you license the Adaptation under one of the licenses mentioned in (iv), you must comply with the terms of that license. If you license the Adaptation under the terms of any of the licenses mentioned in (i), (ii) or (iii) (the "Applicable License"), you must comply with the terms of the Applicable License generally and the following provisions: (I) You must include a copy of, or the URI for, the Applicable License with every copy of each Adaptation You Distribute or Publicly Perform; (II) You may not offer or impose any terms on the Adaptation that restrict the terms of the Applicable License or the ability of the recipient of the Adaptation to exercise the rights granted to that recipient under the terms of the Applicable License; (III) You must keep intact all notices that refer to the Applicable License and to the disclaimer of warranties with every copy of the Work as included in the Adaptation You Distribute or Publicly Perform; (IV) when You Distribute or Publicly Perform the Adaptation, You may not impose any effective technological measures on the Adaptation that restrict the ability of a recipient of the Adaptation from You to exercise the rights granted to that recipient under the terms of the Applicable License. This Section 4(b) applies to the Adaptation as incorporated in a Collection, but this does not require the Collection apart from the Adaptation itself to be made subject to the terms of the Applicable License.
If You Distribute, or Publicly Perform the Work or any Adaptations or Collections, You must, unless a request has been made pursuant to Section 4(a), keep intact all copyright notices for the Work and provide, reasonable to the medium or means You are utilizing: (i) the name of the Original Author (or pseudonym, if applicable) if supplied, and/or if the Original Author and/or Licensor designate another party or parties (e.g., a sponsor institute, publishing entity, journal) for attribution ("Attribution Parties") in Licensor's copyright notice, terms of service or by other reasonable means, the name of such party or parties; (ii) the title of the Work if supplied; (iii) to the extent reasonably practicable, the URI, if any, that Licensor specifies to be associated with the Work, unless such URI does not refer to the copyright notice or licensing information for the Work; and (iv) , consistent with Ssection 3(b), in the case of an Adaptation, a credit identifying the use of the Work in the Adaptation (e.g., "French translation of the Work by Original Author," or "Screenplay based on original Work by Original Author"). The credit required by this Section 4(c) may be implemented in any reasonable manner; provided, however, that in the case of a Adaptation or Collection, at a minimum such credit will appear, if a credit for all contributing authors of the Adaptation or Collection appears, then as part of these credits and in a manner at least as prominent as the credits for the other contributing authors. For the avoidance of doubt, You may only use the credit required by this Section for the purpose of attribution in the manner set out above and, by exercising Your rights under this License, You may not implicitly or explicitly assert or imply any connection with, sponsorship or endorsement by the Original Author, Licensor and/or Attribution Parties, as appropriate, of You or Your use of the Work, without the separate, express prior written permission of the Original Author, Licensor and/or Attribution Parties.
Except as otherwise agreed in writing by the Licensor or as may be otherwise permitted by applicable law, if You Reproduce, Distribute or Publicly Perform the Work either by itself or as part of any Adaptations or Collections, You must not distort, mutilate, modify or take other derogatory action in relation to the Work which would be prejudicial to the Original Author's honor or reputation. Licensor agrees that in those jurisdictions (e.g. Japan), in which any exercise of the right granted in Section 3(b) of this License (the right to make Adaptations) would be deemed to be a distortion, mutilation, modification or other derogatory action prejudicial to the Original Author's honor and reputation, the Licensor will waive or not assert, as appropriate, this Section, to the fullest extent permitted by the applicable national law, to enable You to reasonably exercise Your right under Section 3(b) of this License (right to make Adaptations) but not otherwise.
5. Representations, Warranties and Disclaimer

UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.

6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

7. Termination

This License and the rights granted hereunder will terminate automatically upon any breach by You of the terms of this License. Individuals or entities who have received Adaptations or Collections from You under this License, however, will not have their licenses terminated provided such individuals or entities remain in full compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will survive any termination of this License.
Subject to the above terms and conditions, the license granted here is perpetual (for the duration of the applicable copyright in the Work). Notwithstanding the above, Licensor reserves the right to release the Work under different license terms or to stop distributing the Work at any time; provided, however that any such election will not serve to withdraw this License (or any other license that has been, or is required to be, granted under the terms of this License), and this License will continue in full force and effect unless terminated as stated above.
8. Miscellaneous

Each time You Distribute or Publicly Perform the Work or a Collection, the Licensor offers to the recipient a license to the Work on the same terms and conditions as the license granted to You under this License.
Each time You Distribute or Publicly Perform an Adaptation, Licensor offers to the recipient a license to the original Work on the same terms and conditions as the license granted to You under this License.
If any provision of this License is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this License, and without further action by the parties to this agreement, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
No term or provision of this License shall be deemed waived and no breach consented to unless such waiver or consent shall be in writing and signed by the party to be charged with such waiver or consent.
This License constitutes the entire agreement between the parties with respect to the Work licensed here. There are no understandings, agreements or representations with respect to the Work not specified here. Licensor shall not be bound by any additional provisions that may appear in any communication from You. This License may not be modified without the mutual written agreement of the Licensor and You.
The rights granted under, and the subject matter referenced, in this License were drafted utilizing the terminology of the Berne Convention for the Protection of Literary and Artistic Works (as amended on September 28, 1979), the Rome Convention of 1961, the WIPO Copyright Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and the Universal Copyright Convention (as revised on July 24, 1971). These rights and subject matter take effect in the relevant jurisdiction in which the License terms are sought to be enforced according to the corresponding provisions of the implementation of those treaty provisions in the applicable national law. If the standard suite of rights granted under applicable copyright law includes additional rights not granted under this License, such additional rights are deemed to be included in the License; this License is not intended to restrict the license of any rights under applicable law.

        ==================
        
        .. _travis : https://travis-ci.org/opentraveldata/geobases
        .. |travis| image:: https://api.travis-ci.org/opentraveldata/geobases.png?branch=develop
        
        
        Introduction
        ------------
        
        This project provides tools to play with geographical
        data. It also works with non-geographical data, except for map visualizations :).
        
        There are embedded data sources in the project,
        but you can easily play with your own data in addition to the available ones.
        After data loading, you can:
        
        -  perform various types of queries (find *this key*, or find keys with *this property*)
        -  make *fuzzy searches* based on string distance (find things roughly *named like this*)
        -  make *phonetic searches* (find things *sounding like this*)
        -  make *geographical searches* (find things *next to this place*)
        -  get results on a map, or export it as csv data, or as a Python object
        
        This is entirely written in Python. The core part is a Python package,
        but there is a command line tool as well! Get it with *easy_install*,
        then you can see where are airports with *international* in their name:
        
        .. code-block:: bash
        
         $ GeoBase --fuzzy international --map
        
        .. figure:: https://raw.github.com/opentraveldata/geobases/public/examples/GeoBases-map-points.png
           :align: center
        
        You can perform all types of queries:
        
        .. code-block:: bash
        
         $ GeoBase --base cities --fuzzy "san francisko" # typo here :)
        
        And of course, you can use your own data:
        
        .. code-block:: bash
        
         $ cat data.csv | GeoBase --near London
        
        We are currently gathering input from the community to define the next version features, so do not hesitate to open issues on the `github page <https://github.com/opentraveldata/geobases>`_.
        
        Project
        -------
        
        Prerequisites
        ~~~~~~~~~~~~~
        
        These prerequisites are very standard packages which are often installed
        by default on Linux distributions. But make sure you have them anyway.
        
        First you need to install *setuptools* (as *root*):
        
        .. code-block:: bash
        
         $ apt-get install python-setuptools    # for debian
         $ yum install python-setuptools.noarch # for fedora
        
        Then you need some basics compilation stuff to compile dependencies (also as *root*):
        
        .. code-block:: bash
        
         $ apt-get install python-dev g++    # for debian
         $ yum install python-devel gcc-c++  # for fedora
        
        Installation
        ~~~~~~~~~~~~
        
        You can install it from `PyPI <http://pypi.python.org/pypi>`_ with:
        
        .. code-block:: bash
        
         $ easy_install --user -U GeoBases
        
        If you want the development version, clone the project from
        `github <https://github.com/opentraveldata/geobases.git>`_:
        
        .. code-block:: bash
        
         $ git clone https://github.com/opentraveldata/geobases.git
        
        Then install the package and its dependencies:
        
        .. code-block:: bash
        
         $ cd geobases
         $ python setup.py install --user # for user space
        
        A standalone script is put in ``~/.local/bin``, to benefit from it, put
        that in your ``~/.bashrc`` or ``~/.zshrc``:
        
        .. code-block:: bash
        
         export PATH=$PATH:$HOME/.local/bin
         export BACKGROUND_COLOR=black # or 'white', your call
        
        Python 3 and Pypy support
        ~~~~~~~~~~~~~~~~~~~~~~~~~
        
        There is *Python 3* and *Pypy* (not so) experimental support, you can try it
        by *changing branch* before installation.
        
        For Python 3, you have to install setuptools and python3-dev as prerequisites, then:
        
        .. code-block:: bash
        
         $ git checkout 3000
         $ python3 setup.py install --user
        
        You can also install the package for Python 3:
        
        .. code-block:: bash
        
         $ easy_install-3.2 --user -U GeoBases3K
        
        For Pypy, after pypy and pypy-dev installation:
        
        .. code-block:: bash
        
         $ git checkout pypy
         $ sudo pypy setup.py install
        
        Autocomplete
        ~~~~~~~~~~~~
        
        If you use zsh and want to benefit from the *autocomplete*, add this to
        your ``~/.zshrc``:
        
        .. code-block:: bash
        
         # Add custom completion scripts
         fpath=(~/.zsh/completion $fpath)
         autoload -U compinit
         compinit
        
        
        Tests
        ~~~~~
        
        Run the tests with:
        
        .. code-block:: bash
        
         $ python test/test_GeoBases.py -v
        
        Quickstart
        ----------
        
        .. code-block:: python
        
         >>> from GeoBases import GeoBase
         >>> geo_o = GeoBase(data='ori_por', verbose=False)
         >>> geo_a = GeoBase(data='airports', verbose=False)
         >>> geo_t = GeoBase(data='stations', verbose=False)
        
        You can provide other values for the *data* parameter.
        All data sources are documented in a single *yaml* file:
        
        -  *data="ori\_por"* will load a local version of
           `this file <https://github.com/opentraveldata/optd/raw/trunk/refdata/ORI/ori_por_public.csv>`_,
           this is the most complete source for airports, use it!
        -  *data="ori\_por\_multi"* is the same as previous, but the key for a
           line is not the iata\_code, but the concatenation of iata\_code and
           location\_type. This feature makes every line unique, whereas
           *ori\_por* can have several lines for one iata\_code
        -  *data="airports"* will use geonames as data source for airports
        -  *data="stations"* will use RFF data, from `the open data
           website <http://www.data.gouv.fr>`_, as data source for french train
           stations
        -  *data="stations\_nls"* will use NLS nomenclature as data source for
           french train stations
        -  *data="stations\_uic"* will use UIC nomenclature as data source for
           french train stations
        -  *data="countries"* will load data on countries
        -  *data="capitals"* will load data on countries capitals
        -  *data="continents"* will load data on continents
        -  *data="timezones"* will load data on timezones
        -  *data="languages"* will load data on languages
        -  *data="cities"* will load data on cities, extracted from geonames
        -  *data="currencies"* will load data on currencies, extracted from
           wikipedia
        -  *data="airlines"* will load data on airlines, extracted from
           `that file <https://raw.github.com/opentraveldata/optd/trunk/refdata/ORI/ori_airlines.csv>`_
        -  *data="cabins"* will load data on cabins
        -  *data="locales"* will load data on locales
        -  *data="location\_types"* will load data on location types
        -  *data="feature\_classes"* will load data on feature classes
        -  *data="feature\_codes"* will load data on feature codes
        -  *data="ori\_por\_non\_iata"* will load some non-iata data excluded
           from *ori\_por*
        -  *data="geonames\_MC"* will load MC data of geonames
        -  *data="geonames\_FR"* will load FR data of geonames
        -  *data="postal\_codes\_MC"* will load MC postal codes data
        -  *data="postal\_codes\_FR"* will load FR postal codes data
        -  *data="feed"* will create an empty instance
        
        All features are unaware of the underlying data, and are available as long as
        the headers are properly set in the configuration file, or from the `Python API <https://geobases.readthedocs.org>`_.
        For geographical features, you have to name the latitude field ``lat``, and the
        longitude field ``lng``.
        
        Features
        --------

        You can put your own data in a ``GeoBase`` class, either by loading
        your own file when creating the instance, or by creating an empty instance
        and using the ``set`` method.

        Documentation
        -------------
        
        Here is the `API documentation <https://geobases.readthedocs.org>`_ for the Python package.
        Check out the `wiki <https://github.com/opentraveldata/geobases/wiki>`_ for any question!
        
        Standalone script
        -----------------
        
        Installation of the package will also deploy a standalone script named ``GeoBase``:
        
        .. code-block:: bash
        
         $ GeoBase ORY CDG              # query on the keys ORY and CDG
         $ GeoBase --closest CDG        # closest from CDG
         $ GeoBase --near LIG           # near LIG
         $ GeoBase --fuzzy marseille    # fuzzy search on 'marseille'
         $ GeoBase --help               # your best friend
        
        .. figure:: https://raw.github.com/opentraveldata/geobases/public/examples/GeoBases-CLI.png
           :align: center
        
        In the previous picture, you have an overview of the command line verbose display.
        Three displays are available for the command line tool:
        
        -  the verbose display
        -  the csv display with ``--quiet``
        -  the map display with ``--map``
        
        With the verbose display, entries are displayed on each column,
        and the available fields on each line. Fields starting with ``__`` like ``__field__`` are
        special. This means they were added during data loading:
        
        -  ``__key__`` is the field containing the *id* of the entry. Ids are defined with a list of fields
           in the configuration file.
        -  ``__dup__`` is the field containing a list of duplicated keys. Indeed there is mechanism
           handling duplicated keys by default, which creates new keys if the key already exists in the
           ``GeoBase``.
        -  ``__par__`` is the field containing the parent key if the key is duplicated.
        -  ``__lno__`` is the field containing the line number during loading.
        -  ``__gar__`` is the field containing the data which was not loaded on the line (this can be because
           the line was not well formatted, or because there were missing headers).
        
        More examples here, for example how to do a search on a field, like admin\_code (``B8`` is french riviera):
        
        .. code-block:: bash
        
         $ GeoBase -E adm1_code -e B8
        
        Same with csv output (customized with ``--show``):
        
        .. code-block:: bash
        
         $ GeoBase -E adm1_code -e B8 --quiet --show __ref__ iata_code  name
        
        Add a fuzzy search:
        
        .. code-block:: bash
        
         $ GeoBase -E adm1_code -e B8 --fuzzy sur mer
        
        All heliports under 200 km from Paris:
        
        .. code-block:: bash
        
         $ GeoBase --near PAR -N 200 -E location_type -e 'H'
        
        50 train stations closest to a specific geocode:
        
        .. code-block:: bash
        
         $ GeoBase -E location_type -e R --closest '48.853, 2.348' -C 50
        
        Countries with non-empty postal code regex:
        
        .. code-block:: bash
        
         $ GeoBase -b countries -E postal_code_regex -e '' --reverse --quiet
        
        Reading data input on stdin:
        
        .. code-block:: bash
        
         $ echo -e 'ORY^Orly\nCDG^Charles' | GeoBase
        
        Display on map:
        
        .. code-block:: bash
        
         $ GeoBase -b stations --map
        
        Marker-less map for a specific GMT offset:
        
        .. code-block:: bash
        
         $ GeoBase -E gmt_offset -e 1.0 --map -M _ _ country_code  __none__
        
        
        Packaging
        ---------
        
        The ``MANIFEST.in`` file is used to determine which files will be
        included in a source distribution.
        ``package_data`` directive in ``setup.py`` file is about which file will
        be exported in site-package after installation.
        So you really need both if you want to produce installable packages like
        rpms or zip which can be installed afterwards.
        
        You will also find a `Rakefile <http://rake.rubyforge.org/>`_ at the
        root of the project. This can be used to build and deploy the packages.
        Deployment can be done using webdav, and the Rakefile expects ``nd`` to be
        installed (this is a webdav client).
        To install ``nd``, fetch the `sources <http://www.gohome.org/nd/>`_ and compile them.
        
        Virtualenv still has some bugs on 64 bits systems, if you are using such a system,
        you absolutely need to upgrade to the very last unreleased version of
        virtualenv, before executing rake:
        
        .. code-block:: bash
        
         $ pip uninstall virtualenv
         $ pip install https://github.com/pypa/virtualenv/tarball/develop
