   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

   1. Definitions.

      "License" shall mean the terms and conditions for use, reproduction,
      and distribution as defined by Sections 1 through 9 of this document.

      "Licensor" shall mean the copyright owner or entity authorized by
      the copyright owner that is granting the License.

      "Legal Entity" shall mean the union of the acting entity and all
      other entities that control, are controlled by, or are under common
      control with that entity. For the purposes of this definition,
      "control" means (i) the power, direct or indirect, to cause the
      direction or management of such entity, whether by contract or
      otherwise, or (ii) ownership of fifty percent (50%) or more of the
      outstanding shares, or (iii) beneficial ownership of such entity.

      "You" (or "Your") shall mean an individual or Legal Entity
      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

Eigen

From the Eigen Licensing page
(http://eigen.tuxfamily.org/index.php?title=Main_Page)

Eigen is Free Software. Starting from the 3.1.1 version, it is licensed 
under the MPL2, which is a simple weak copyleft license.  Common 
questions about the MPL2 are answered in the official MPL2 FAQ 
(http://www.mozilla.org/MPL/2.0/FAQ.html).

Note that currently, a few features rely on third-party code licensed 
under the LGPL: SimplicialCholesky, AMD ordering, and constrained_cg. 
Such features can be explicitly disabled by compiling with the 
EIGEN_MPL2_ONLY preprocessor symbol defined.   

Virtually any software may use Eigen. For example, closed-source 
software may use Eigen without having to disclose its own source code. 
Many proprietary and closed-source software projects are using Eigen 
right now, as well as many BSD-licensed projects.

• under intellectual property rights (other than patent or trademark) 
Licensable by such Contributor to use, reproduce, make available, 
modify, display, perform, distribute, and otherwise exploit its

2.2. Effective Date

The licenses granted in Section 2.1 with respect to any Contribution 
become effective for each Contribution on the date the Contributor 
first distributes such Contribution.

2.3. Limitations on Grant Scope

The licenses granted in this Section 2 are the only rights granted 
under this License. No additional rights or licenses will be implied 
from the distribution or licensing of Covered Software under this 
License. Notwithstanding Section 2.1(b) above, no patent license is 
granted by a Contributor:

• for any code that a Contributor has removed from Covered Software; 
or

• for infringements caused by: (i) Your and any other third party’s 
modifications of Covered Software, or (ii) the combination of its 
Contributions with other software (except as part of its Contributor 
Version); or

• under Patent Claims infringed by Covered Software in the absence of 
its Contributions.

This License does not grant any rights in the trademarks, service 
marks, or logos of any Contributor (except as may be necessary to 
comply with the notice requirements in Section 3.4).

2.4. Subsequent Licenses

No Contributor makes additional grants as a result of Your choice to 
distribute the Covered Software under a subsequent version of this 
License (see Section 10.2) or under the terms of a Secondary License 
(if permitted under the terms of Section 3.3).

2.5. Representation

Each Contributor represents that the Contributor believes its 
Contributions are its original creation(s) or it has sufficient rights 
to grant the rights to its Contributions conveyed by this License.

2.6. Fair Use

This License is not intended to limit any rights You have under 
applicable copyright doctrines of fair use, fair dealing, or other 
equivalents.

2.7. Conditions

Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted 
in Section 2.1.

3. Responsibilities

3.1. Distribution of Source Form

All distribution of Covered Software in Source Code Form, including any 
Modifications that You create or to which You contribute, must be under 
the terms of this License. You must inform recipients that the Source 
Code Form of the Covered Software is governed by the terms of this 
License, and how they can obtain a copy of this License. You may not 
attempt to alter or restrict the recipients’ rights in the Source Code 
Form.

3.2. Distribution of Executable Form

If You distribute Covered Software in Executable Form then:

• such Covered Software must also be made available in Source Code 
Form, as described in Section 3.1, and You must inform recipients of 
the Executable Form how they can obtain a copy of such Source Code Form 
by reasonable means in a timely manner, at a charge no more than the 
cost of distribution to the recipient; and

• You may distribute such Executable Form under the terms of this 
License, or sublicense it under different terms, provided that the 
license for the Executable Form does not attempt to limit or alter the 
recipients’ rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

You may create and distribute a Larger Work under terms of Your choice, 
provided that You also comply with the requirements of this License for 
the Covered Software. If the Larger Work is a combination of Covered 
Software with a work governed by one or more Secondary Licenses, and 
the Covered Software is not Incompatible With Secondary Licenses, this 
License permits You to additionally distribute such Covered Software 
under the terms of such Secondary License(s), so that the recipient of 
the Larger Work may, at their option, further distribute the Covered 
Software under the terms of either this License or such Secondary 
License(s).

3.4. Notices

You may not remove or alter the substance of any license notices 
(including copyright notices, patent notices, disclaimers of warranty, 
or limitations of liability) contained within the Source Code Form of 
the Covered Software, except that You may alter any license notices to 
the extent required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

You may choose to offer, and to charge a fee for, warranty, support, 
indemnity or liability obligations to one or more recipients of Covered 
Software. However, You may do so only on Your own behalf, and not on 
behalf of any Contributor. You must make it absolutely clear that any 
such warranty, support, indemnity, or liability obligation is offered 
by You alone, and You hereby agree to indemnify every Contributor for 
any liability incurred by such Contributor as a result of warranty, 
support, indemnity or liability terms You offer. You may include 
additional disclaimers of warranty and limitations of liability 
specific to any jurisdiction.

4. Inability to Comply Due to Statute or Regulation

If it is impossible for You to comply with any of the terms of this 
License with respect to some or all of the Covered Software due to 
statute, judicial order, or regulation then You must: (a) comply with  
the terms of this License to the maximum extent possible; and (b) 
describe the limitations and the code they affect. Such description 
must be placed in a text file included with all distributions of the 
Covered Software under this License. Except to the extent prohibited 
by statute or regulation, such description must be sufficiently 
detailed for a recipient of ordinary skill to be able to understand it.

5. Termination

5.1. The rights granted under this License will terminate automatically 
if You fail to comply with any of its terms. However, if You become 
compliant, then the rights granted under this License from a  
particular Contributor are reinstated (a) provisionally, unless and 
until such Contributor explicitly and finally terminates Your grants, 
and (b) on an ongoing basis, if such Contributor fails to notify You 
of the non-compliance by some reasonable means prior to 60 days after 
You have come back into compliance. Moreover, Your grants from a 
particular Contributor are reinstated on an ongoing basis if such 
Contributor notifies You of the non-compliance by some reasonable 
means, this is the first time You have received notice of 
non-compliance with this License from such Contributor, and You become 
compliant prior to 30 days after Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a 
patent infringement claim (excluding declaratory judgment actions, 
counter-claims, and cross-claims) alleging that a Contributor Version 
directly or indirectly infringes any patent, then the rights granted to 
You by any and all Contributors for the Covered Software under Section 
2.1 of this License shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all 
end user license agreements (excluding distributors and resellers)
which have been validly granted by You or Your distributors under this 
License prior to termination shall survive termination.

6. Disclaimer of Warranty

Covered Software is provided under this License on an “as is” 
basis, without warranty of any kind, either expressed, implied, or 
statutory, including, without limitation, warranties that the Covered 
Software is free of defects, merchantable, fit for a particular purpose 
or non-infringing. The entire risk as to the quality and performance of 
the Covered Software is with You. Should any Covered Software prove 
defective in any respect, You (not any Contributor) assume the cost of 
any necessary servicing, repair, or correction. This disclaimer of 
warranty constitutes an essential part of this License. No use of any 
Covered Software is authorized under this License except under this 
disclaimer.

7. Limitation of Liability

Under no circumstances and under no legal theory, whether tort 
(including negligence), contract, or otherwise, shall any Contributor, 
or anyone who distributes Covered Software as permitted above, be 
liable to You for any direct, indirect, special, incidental, or 
consequential damages of any character including, without limitation, 
damages for lost profits, loss of goodwill, work stoppage, computer 
failure or malfunction, or any and all other commercial damages or 
losses, even if such party shall have been informed of the possibility 
of such damages. This limitation of liability shall not apply to 
liability for death or personal injury resulting from such party’s 
negligence to the extent applicable law prohibits such limitation. Some 
jurisdictions do not allow the exclusion or limitation of incidental or 
consequential damages, so this exclusion and limitation may not apply 
to You.

8. Litigation

Any litigation relating to this License may be brought only in the 
courts of a jurisdiction where the defendant maintains its principal 
place of business and such litigation shall be governed by laws of that 
jurisdiction, without reference to its conflict-of-law provisions. 
Nothing in this Section shall prevent a party’s ability to bring 
cross-claims or counter-claims.

9. Miscellaneous

This License represents the complete agreement concerning the subject 
matter hereof. If any provision of this License is held to be 
unenforceable, such provision shall be reformed only to the extent  
necessary to make it enforceable. Any law or regulation which provides 
that the language of a contract shall be construed against the drafter 
shall not be used to construe this License against a Contributor.

10. Versions of the License

10.1. New Versions

Mozilla Foundation is the license steward. Except as provided in 
Section 10.3, no one other than the license steward has the right to 
modify or publish new versions of this License. Each version will be 
given a distinguishing version number.

10.2. Effect of New Versions

You may distribute the Covered Software under the terms of the version 
of the License under which You originally received the Covered 
Software, or under the terms of any subsequent version published by the 
license steward.

10.3. Modified Versions

If you create software not governed by this License, and you want to 
create a new license for such software, you may create and use a 
modified version of this License if you rename the license and remove 
any references to the name of the license steward (except to note that 
such modified license differs from this License).

MADlib builds Eigen using the EIGEN_MPL2_ONLY flag enabled.

std::ctype<char>::_M_widen_init() is a function authored by Jerry Quinn
<jlquinn@optonline.net>, which was added to libstdc++ with revision 74662 on
Dec 16, 2003 [1].

With permission from Jerry (thankfully received on Oct 9, 2012), we include a
copy of this function in the MADlib repository. The sole intention is to allow
compiling MADlib with recent versions of gcc while still keeping the runtime
dependencies limited to earlier versions of libstdc++. Technical details are
given in src/utils/libstdcxx-compatibility.cpp.

Revision 74662 of the libstdc++-v3 file include/bits/locale_facets.h, where
std::ctype<char>::_M_widen_init() has been copied from, also included the
following notice in the file header [2]:

argparse is (c) 2006-2009 Steven J. Bethard <steven.bethard@gmail.com>.

The argparse module was contributed to Python as of Python 2.7 and thus
was licensed under the Python license. Same license applies to all files in
the argparse package project.

For details about the Python License, please see Python_License_v2.7.1.txt.

History
-------

Before (and including) argparse 1.1, the argparse package was licensed under
Apache License v2.0.

After argparse 1.1, all project files from the argparse project were deleted
due to license compatibility issues between Apache License 2.0 and GNU GPL v2.

The project repository then had a clean start with some files taken from
Python 2.7.1, so definitely all files are under Python License now.
