<h1 align="center">ICU Copyrights</h1>
<p>The ICU project files contain code with several kinds of copyrights. They fall into several categories:</p>
<blockquote>
<p><i>Copyright <date> IBM and others<br>
</i>This is the standard copyright notice that was specified by the
IBM Public License. All IBM-developed code in ICU4C and ICU4J will
contain this notice. In the vast majority of cases — even where
they say "and others" — files do not actually have any other
contributions other than from IBM. See <a href="contributions/code_contributions.html">Code Contributions</a>.
</p>
<p><i>Copyright <date> <contributor> and others<br>
</i>Outside developers or companies who are allowed to contribute
code to ICU may have their own copyright statements. However, all
material contributions are covered by a copyright agreement. See <a href="contributions/code_contributions.html">Code Contributions</a>.
</p>
<p><i>Copyright <date> Free Software Foundation<br>
</i>ICU4C (not ICU4J) contains three build scripts with FSF copyrights: <code>configure</code>, <code>config.sub</code>, and <code>config.guess</code>.
This often causes confusion, because most FSF code is covered by the
GNU license, which is viral. These three files, however, contain
explicit statements that they are not covered by the GPL when
distributed as part of other projects, and that they may be
redistributed under other licenses. For details, see <a href="#FSF">FSF</a>.
</p>
<p><i>Copyright <date> Massachusetts Institute of Technology<br>
</i>ICU4C (not ICU4J) contains one file, <code>install-sh</code>, with an MIT copyright. However, the file includes an explicit header saying that it can be redistributed without fee. For
details, see <a href="#MIT">MIT</a>.</p>
<p><span style="font-style: italic;">Public Domain</span><br>
ICU4C (not ICU4J) contains three files: zic.c, tzfile.h and
tzselect.ksh that are in the public domain as clarified by the authors
and notices in the files.
</p>
<h3>Data Files</h3>
<p><i># Copyright (c) <date> Unicode, Inc.<br>
</i>As of Unicode 4.0.1, the license terms have been made more
explicit on the files that we redistribute from the Unicode Character
Database. This permitted is under the terms of the license. For
details, see <a href="#UCD">UCD</a>.</p>
</blockquote>

<h2><a name="Details">Details</a></h2>
<p>Note: The text in <code>typewriter style</code> (mostly with a # character at
the beginning of the lines) directly under filename links is quoted directly
from those files. It shows the full copyright information from those files.</p>
<h3>A. <a name="FSF">Free Software Foundation</a></h3>
<blockquote>
<p><u>Applies to ICU4C. Does not apply to ICU4J.</u></p>
<p>Do not distribute the files mentioned in this section in a product, with
binary executables. These files are used only in the ICU build process and are
therefore part of the source code repository and source downloads but are not
needed for product installation.</p>
<p>The statements for two of the files under "Free Software Foundation" are the following. Note that we do "<i>distribute
this file as part of a program that contains a configuration script generated by
Autoconf</i>" and therefore we "include it under the same
distribution terms that you use for the rest of that program" (see bold
quoted text below).</p>
<p>Further details: Development of C/C++ code that is portable across a large
number of platforms and compilers requires adaptation to the many differences
between them. The Autoconf tool achieves this for ICU and for many other
development projects. It needs these script files in order to function. The
files themselves, as published by their authors and quoted below, contain an
exception to the GPL that allows commercial (non-GPL) software development
using these files. The exception requires the distribution of the files. These
files are part of the build setup, not part of the library source code.
Shipping build files is only relevant for source downloads. ICU4C fulfills the
condition by including the required files in its source download.</p>
<p>These files are not used for Java development and therefore do not apply to
ICU4J.</p>
