+# GNU GENERAL PUBLIC LICENSE
+
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to guarantee
+your freedom to share and change free software--to make sure the software is free
+for all its users. This General Public License applies to most of the Free
+Software Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by the GNU
+Lesser General Public License instead.) You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom to
+distribute copies of free software (and charge for this service if you wish),
+that you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs; and that you know you
+can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of the
+software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for
+a fee, you must give the recipients all the rights that you have. You must make
+sure that they, too, receive or can get the source code. And you must show them
+these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If the
+software is modified by someone else and passed on, we want its recipients to
+know that what they have is not the original, so that any problems introduced
+by others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We wish
+to avoid the danger that redistributors of a free program will individually
+obtain patent licenses, in effect making the program proprietary. To prevent
+this, we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification follow.
+
+## TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. 	This License applies to any program or other work which contains a notice
+	placed by the copyright holder saying it may be distributed under the terms of
+	this General Public License. The "Program", below, refers to any such program
+	or work, and a "work based on the Program" means either the Program or any
+	derivative work under copyright law: that is to say, a work containing the
+	Program or a portion of it, either verbatim or with modifications and/or
+	translated into another language. (Hereinafter, translation is included without
+	limitation in the term "modification".) Each licensee is addressed as "you".
+
+	Activities other than copying, distribution and modification are not covered by
+	this License; they are outside its scope. The act of running the Program is not
+	restricted, and the output from the Program is covered only if its contents
+	constitute a work based on the Program (independent of having been made by
+	running the Program). Whether that is true depends on what the Program does.
+
+1. 	You may copy and distribute verbatim copies of the Program's source code as
+	you receive it, in any medium, provided that you conspicuously and appropriately
+	publish on each copy an appropriate copyright notice and disclaimer of warranty;
+	keep intact all the notices that refer to this License and to the absence of any
+	warranty; and give any other recipients of the Program a copy of this License
+	along with the Program.
+
+	You may charge a fee for the physical act of transferring a copy, and you may at
+	your option offer warranty protection in exchange for a fee.
+
+2. 	You may modify your copy or copies of the Program or any portion of it, thus
+	forming a work based on the Program, and copy and distribute such modifications
+	or work under the terms of Section 1 above, provided that you also meet all of
+	these conditions:
+
+	a) You must cause the modified files to carry prominent notices stating that
+	   you changed the files and the date of any change.
+	b) You must cause any work that you distribute or publish, that in whole or in
+	   part contains or is derived from the Program or any part thereof, to be
+	   licensed as a whole at no charge to all third parties under the terms of this
+	   License.
+	c) If the modified program normally reads commands interactively when run, you
+	   must cause it, when started running for such interactive use in the most
+	   ordinary way, to print or display an announcement including an appropriate
+	   copyright notice and a notice that there is no warranty (or else, saying
+	   that you provide a warranty) and that users may redistribute the program
+	   under these conditions, and telling the user how to view a copy of this
+	   License. (Exception: if the Program itself is interactive but does not
+	   normally print such an announcement, your work based on the Program is not
+	   required to print an announcement.)
+
+	These requirements apply to the modified work as a whole. If identifiable
+	sections of that work are not derived from the Program, and can be reasonably
+	considered independent and separate works in themselves, then this License,
+	and its terms, do not apply to those sections when you distribute them as
+	separate works. But when you distribute the same sections as part of a whole
+	which is a work based on the Program, the distribution of the whole must be on
+	the terms of this License, whose permissions for other licensees extend to the
+	entire whole, and thus to each and every part regardless of who wrote it.
+
+	Thus, it is not the intent of this section to claim rights or contest your
+	rights to work written entirely by you; rather, the intent is to exercise the
+	right to control the distribution of derivative or collective works based on
+	the Program.
+
+	In addition, mere aggregation of another work not based on the Program with the
+	Program (or with a work based on the Program) on a volume of a storage or
+	distribution medium does not bring the other work under the scope of this
+	License.
+
+	3. You may copy and distribute the Program (or a work based on it, under
+	Section 2) in object code or executable form under the terms of Sections 1
+	and 2 above provided that you also do one of the following:
+
+	a) Accompany it with the complete corresponding machine-readable source code,
+	   which must be distributed under the terms of Sections 1 and 2 above on a
+	   medium customarily used for software interchange; or,
+	b) Accompany it with a written offer, valid for at least three years, to give
+	   any third party, for a charge no more than your cost of physically
+	   performing source distribution, a complete machine-readable copy of the
+	   corresponding source code, to be distributed under the terms of Sections 1
+	   and 2 above on a medium customarily used for software interchange; or,
+	c) Accompany it with the information you received as to the offer to distribute
+	   corresponding source code. (This alternative is allowed only for
+	   noncommercial distribution and only if you received the program in object
+	   code or executable form with such an offer, in accord with Subsection b
+	   above.)
+
+	The source code for a work means the preferred form of the work for making
+	modifications to it. For an executable work, complete source code means all the
+	source code for all modules it contains, plus any associated interface
+	definition files, plus the scripts used to control compilation and installation
+	of the executable. However, as a special exception, the source code distributed
+	need not include anything that is normally distributed (in either source or
+	binary form) with the major components (compiler, kernel, and so on) of the
+	operating system on which the executable runs, unless that component itself
+	accompanies the executable.
+
+	If distribution of executable or object code is made by offering access to
+	copy from a designated place, then offering equivalent access to copy the
+	source code from the same place counts as distribution of the source code,
+	even though third parties are not compelled to copy the source along with the
+	object code.
+
+4. 	You may not copy, modify, sublicense, or distribute the Program except as
+	expressly provided under this License. Any attempt otherwise to copy, modify,
+	sublicense or distribute the Program is void, and will automatically
+	terminate your rights under this License. However, parties who have
+	received copies, or rights, from you under this License will not have their
+	licenses terminated so long as such parties remain in full compliance.
+
+5. 	You are not required to accept this License, since you have not signed it.
+	However, nothing else grants you permission to modify or distribute the
+	Program or its derivative works. These actions are prohibited by law if
+	you do not accept this License. Therefore, by modifying or distributing
+	the Program (or any work based on the Program), you indicate your
+	acceptance of this License to do so, and all its terms and conditions
+	for copying, distributing or modifying the Program or works based on it.
+
+6. 	Each time you redistribute the Program (or any work based on the Program),
+	the recipient automatically receives a license from the original licensor
+	to copy, distribute or modify the Program subject to these terms and
+	conditions. You may not impose any further restrictions on the recipients'
+	exercise of the rights granted herein. You are not responsible for enforcing
+	compliance by third parties to this License.
+
+7.  If, as a consequence of a court judgment or allegation of patent infringement
+	or for any other reason (not limited to patent issues), conditions are
+	imposed on you (whether by court order, agreement or otherwise) that
+	contradict the conditions of this License, they do not excuse you from the
+	conditions of this License. If you cannot distribute so as to satisfy
+	simultaneously your obligations under this License and any other pertinent
+	obligations, then as a consequence you may not distribute the Program at
+	all. For example, if a patent license would not permit royalty-free
+	redistribution of the Program by all those who receive copies directly or
+	indirectly through you, then the only way you could satisfy both it and
+	this License would be to refrain entirely from distribution of the Program.
+
+	If any portion of this section is held invalid or unenforceable under any
+	particular circumstance, the balance of the section is intended to apply
+	and the section as a whole is intended to apply in other circumstances.
+
+	It is not the purpose of this section to induce you to infringe any patents
+	or other property right claims or to contest validity of any such claims;
+	this section has the sole purpose of protecting the integrity of the free
+	software distribution system, which is implemented by public license
+	practices. Many people have made generous contributions to the wide range
+	of software distributed through that system in reliance on consistent
+	application of that system; it is up to the author/donor to decide if he or
+	she is willing to distribute software through any other system and a
+	licensee cannot impose that choice.
+
+	This section is intended to make thoroughly clear what is believed to be a
+	consequence of the rest of this License.
+
+8. 	If the distribution and/or use of the Program is restricted in certain
+	countries either by patents or by copyrighted interfaces, the original
+	copyright holder who places the Program under this License may add an
+	explicit geographical distribution limitation excluding those countries,
+	so that distribution is permitted only in or among countries not thus
+	excluded. In such case, this License incorporates the limitation as if
+	written in the body of this License.
+
+9. 	The Free Software Foundation may publish revised and/or new versions of the
+	General Public License from time to time. Such new versions will be similar
+	in spirit to the present version, but may differ in detail to address new
+	problems or concerns.
+
+	Each version is given a distinguishing version number. If the Program
+	specifies a version number of this License which applies to it and
+	"any later version", you have the option of following the terms and
+	conditions either of that version or of any later version published
+	by the Free Software Foundation. If the Program does not specify a version
+	number of this License, you may choose any version ever published by the
+	Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs
+	whose distribution conditions are different, write to the author to ask for
+	permission. For software which is copyrighted by the Free Software
+	Foundation, write to the Free Software Foundation; we sometimes make
+	exceptions for this. Our decision will be guided by the two goals of
+	preserving the free status of all derivatives of our free software and of
+	promoting the sharing and reuse of software generally.
+
+NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+	THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+	OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+	PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+	OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+	MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO
+	THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+	PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+	CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+	ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
+	THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+	GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+	USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+	DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+	PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+	EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+	SUCH DAMAGES.

+# csv2edn
+
+Simple command line utility to convert CSV files to EDN. Assumes the first row of a CSV file contains column headers.
+
+## Installation
+
+Download from http://example.com/FIXME.
+
+## Usage
+
+FIXME: explanation
+
+    $ java -jar csv2edn-0.1.0-standalone.jar [args]
+
+## Options
+
+Where args are:
+
+    -h, --help                    Print this message and exit.
+    -i, --input INPUT             The path name of the CSV file to be read.
+      If no input file is specified, input will be read from standard input.
+    -o, --output OUTPUT           The path name of the EDN file to be written.
+      If no output file is specified, output will be written to standard output.
+    -s, --separator SEPARATOR     The character to treat as a separator in the
+      CSV file. If not specified, comma will be used by default.
+
+
+FIXME: listing of options this app accepts.
+
+## Examples
+
+The simplest possible use is to simply use this in a pipeline:
+
+    $ cat path/to/file.csv |\
+        java -jar csv2edn-0.1.0-standalone.jar > path/to/file.edn
+
+Exactly the same behaviour can be achieved by specifying input and output
+paths:
+
+    $ java -jar csv2edn-0.1.0-standalone.jar \
+        -i path/to/file.csv -o path/to/file.edn
+
+or
+
+    $ java -jar csv2edn-0.1.0-standalone.jar \
+        --input path/to/file.csv --output path/to/file.edn
