Update to legal notice, made Feb 2012, modified Sep 2013. We would like to
clarify that we are using a convention where multiple names in the Apache
copyright headers, for example
// Copyright 2009-2012 Yanmin Qian Arnab Ghoshal
// 2013 Vassil Panayotov
does not signify joint ownership of copyright of that file, except in cases
where all those names were present in the original release made in March 2011--
you can use the version history to work this out, if this matters to you.
Instead, we intend that those contributors who later modified the file, agree
to release their changes under the Apache license. The conventional way of
signifying this is to duplicate the Apache headers at the top of each file each
time a change is made by a different author, but this would quickly become
impractical.
Where the copyright header says something like:
// Copyright 2013 Johns Hopkins University (author: Daniel Povey)
it is because the individual who wrote the code was at that institution as an
employee, so the copyright is owned by the university (and we will have checked
that the contributions were in accordance with the open-source policies of the
institutions concerned, including getting them vetted individually where
necessary). From a legal point of view the copyright ownership is that of the
institution concerned, and the (author: xxx) in parentheses is just
informational, to identify the actual person who wrote the code, and is not
intended to have any legal implications. In some cases, however, particularly
early on, we just wrote the name of the university or company concerned,
without the actual author's name in parentheses. If you see something like
// Copyright 2009-2012 Arnab Ghoshal Microsoft Corporation
it does not imply that Arnab was working for Microsoft, it is because someone
else contributed to the file while working at Microsoft (this would be Daniel
Povey, in fact, who was working at Microsoft Research at the outset of the
project).
The list of authors of each file is in an essentially arbitrary order, but is
often chronological if they contributed in different years.
The original legal notice is below. Note: we are continuing to modify it by
adding the names of new contributors, but at any given time, the list may
be out of date.

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

(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

modifications, and in Source or Object form, provided that You

(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

documentation, if provided along with the Derivative Works; or,

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

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
