Overview

The ABOUT tool and ABOUT files provide a simple way to document the provenance 
(origin and license) and other important or interesting information about 
third-party software components that you use in your project. 

You start by storing ABOUT files (a small text file with field/value pairs) 
side-by-side with each of the third-party software components you use.
Each ABOUT file documents one software component origin and license.
For more information on the ABOUT file format, visit http://www.dejacode.org
There are many examples of ABOUT files (valid or invalid) in the testdata 
directory of the whole repository.

The current version of the ABOUT tool can read these ABOUT files so that you 
can collect and validate the inventory of third-party components that you use.

In future versions, this tool will be able to generate attribution notices and 
collect redistributable source code used in your project to help you comply 
with open source licenses requirements. 

This version of the ABOUT tool follows the ABOUT specification version 0.8.0 at:

REQUIREMENTS
------------
The ABOUT tool has been tested with Python 2.6 or 2.7 on Linux, Mac and Windows.
You will need to install a Python interpreter if you do not have one already 
installed.

On Linux and Mac, Python is typically pre-installed. To verify which 
version may be pre-installed, open a terminal and type:
    python --version
    python2.6 --version
    python2.7 --version

On Windows or Mac, you can download Python 2.6 here: 
    http://www.python.org/download/releases/2.6.6/

or Python 2.7 here:
    http://www.python.org/download/releases/2.7.5/

Download the .msi installer for Windows or the .dmg archive for Mac.
Open and run the installer using all the default options.


INSTALLATION

TESTS
-----
Optionally, to verify that everything works fine you can run the test suite, 
download the whole repository at:

Then open a terminal or command prompt, extract the download if needed and run::

    python tests.py


USAGE
-----

The ABOUT tool command syntax is::

    $ python about.py [--options] <input> <output>

    [--options]
        --overwrite     Overwrites the output file if it exists
        -v,--version    Display current version, license notice, and copyright notice
        -h,--help       Display syntx help

    <input> - Path location where the .ABOUT file(s) located.
              The location can be pointing to a file or directory.

    <output> - Path location where the generated output will be saved. 
               The <output> must be a path with an output filename ending 
               with the ".csv" extension.

Example::
    $ python about.py ./thirdparty_code/ thirdparty_about.csv


In this example, the .ABOUT files in the directory /thirdparty_code/ will 
be parsed and validated to collect the data they contain. The collected 
information will be saved to the CSV file named "thirdparty_about.csv".
