 *
 *  This documentation describes the functions, classes and related
 *  entities in the C++ calculation engine, as well as how these can
 *  be accessed through Python.
 *
 *  This API documentation is written in terms of C++.
 *  However, Python programmers can use exactly the same functions,
 *  classes, methods and so on.  If the Python version of a function
 *  differs from the C++ version, you will see a bold <b>Python:</b> note
 *  telling you how it differs.
 *
 *  To start: visit the <a href="modules.html">Modules</a> page and take
 *  a look around, or browse through the classes regina::NTriangulation and
 *  regina::NNormalSurfaceList.
 *
 *  <h3>Citation</h3>

 *
 *  <h3>Online Distribution</h3>
 *
 *  Regina's own source code comes with the following permissions in
 *  addition to the GNU General Public License:
 *
 *  As an exception, when this program is distributed through (i) the
 *  App Store by Apple Inc.; (ii) the Mac App Store by Apple Inc.; or
 *  (iii) Google Play by Google Inc., then that store may impose any
 *  digital rights management, device limits and/or redistribution
 *  restrictions that are required by its terms of service.
 *
 *  Some third-party libraries included in Regina are not granted this
 *  exception, and must be removed from any build that is distributed on
 *  stores that cannot comply with the GNU General Public License (such as
 *  Apple's App Store).  See the third-party licenses below for details.
 *
 *  <h3>SnapPea and SnapPy</h3>
 *
 *  Regina includes portions of the SnapPea kernel and its successor SnapPy,
 *  which it uses for some geometric calculations.  The SnapPea kernel was
 *  written by Jeff Weeks, and SnapPy was written by Marc Culler, Nathan
 *  Dunfield, and others.  SnapPy and the corresponding SnapPea kernel are
 *  distributed under the terms of the GNU General Public License, version 2
 *  or any later version, as published by the Free Software Foundation.
 *
 *  <h3>Normaliz Library</h3>
 *
 *  Regina includes a copy of libnormaliz, which it uses to help with the
 *  enumeration of fundamental normal surfaces.  Normaliz was written by
 *  Winfried Bruns, Bogdan Ichim and Christof Soeger.  It is distributed
 *  under the terms of the GNU General Public License as published by the
 *  Free Software Foundation, either version 3 of the License, or (at your
 *  option) any later version.
 *
 *  <h3>Orb Kernel</h3>
 *
 *  Regina includes snippets of code from Orb, for use in importing and
 *  exporting files in Orb / Casson format.  Orb is based on SnapPea
 *  (see above) with additional code written by Damian Heard, who has also
 *  given permission for his code to be distributed under the terms of the
 *  GNU General Public License.

/*! \page i18n Encodings for international strings
 *
 *  As of version 4.5, Regina (finally) pays attention to character encodings.
 *
 *  The calculation engine uses UTF-8 for all strings (except possibly
 *  for filenames; see below).  This means that programmers who pass
 *  strings \e into routines must ensure that they use UTF-8, and
 *  programmers who receive strings \e from routines may assume that
 *  they are returned in UTF-8.  Note that plain ASCII is a subset of
 *  UTF-8, so plain ASCII text is always fine to use.
 *
 *  Regina's XML data files are also stored using UTF-8.  Older
 *  versions of Regina used LATIN1 (the default for the Qt libraries)
 *  and did not specify an encoding in the XML header; however, Regina's
 *  file I/O routines are aware of this, and will convert older data into
 *  UTF-8 as it is loaded into memory (the files themselves are
 *  of course not modified).  The routine versionUsesUTF8() may be
 *  useful for programmers who need to work with older data files at a
 *  low level.
 *
 *  File \e names are a special case, since here Regina must interact with
 *  the underlying operating system.  All filenames that are passed into
 *  routines must be presented in whatever encoding the operating system
 *  expects; Regina will simply pass them through to the standard C/C++ file
 *  I/O routines (such as fopen() or std::ifstream::open()) without modifying
 *  them in any way.
 *
 *  It should be noted that ancient data files that use the old binary
 *  format (Regina 2.x, before mid-2002) only support plain ASCII text.
 *  Support for the old binary format is likely to be removed entirely in the
 *  very near future.
 *
 *  \ifacespython Users and programmers who use the Python interface must
 *  take special care, since Python does not pass strings around in UTF-8
 *  by default.
 *
 *  Proper support for character encodings is quite new, and the main
 *  author rarely uses this (being a native English speaker).  If you
 *  see Regina treating international characters in unexpected ways,
 *  please mail the author(s) or file a bug report so the problem can be
 *  fixed!
