 <title>About Cygwin</title>

 <qandaentry id="faq.what.what">
 <question><para>What is it?</para></question>
 <answer>

 <para>Cygwin is a distribution of popular GNU and other Open Source tools
 running on Microsoft Windows.  The core part is the Cygwin library which
 provides the POSIX system calls and environment these programs expect.
 </para>
 <para>The Cygwin distribution contains thousands of packages from the Open
 Source world including most GNU tools, many BSD tools, an X server and a full
 set of X applications.  If you're a developer you will find tools, headers
 and libraries allowing to write Windows console or GUI applications that make
 use of significant parts of the POSIX API.  Cygwin allows easy porting of many
 Unix programs without the need for extensive changes to the source code.  This
 includes configuring and building most of the available GNU or BSD software,
 including the packages included with the Cygwin distribution themselves.
 They can be used from one of the provided Unix shells like bash, tcsh or zsh.
 </para>
 </answer></qandaentry>

 <qandaentry id="faq.what.supported">
 <question><para>What versions of Windows are supported?</para></question>
 <answer>

 <para>Cygwin can be expected to run on all modern, released versions of Windows.
 State January 2016 this includes Windows Vista, Windows Server 2008 and all
 later versions of Windows up to Windows 10 and Windows Server 2016.
 The 32 bit version of Cygwin also runs in the WOW64 32 bit environment on
 released 64 bit versions of Windows, the 64 bit version of course only on
 64 bit Windows.
 </para>
 <para>Keep in mind that Cygwin can only do as much as the underlying OS
 supports.  Because of this, Cygwin will behave differently, and
 exhibit different limitations, on the various versions of Windows.
 </para>
 </answer></qandaentry>

 <qandaentry id="faq.what.where">
 <question><para>Where can I get it?</para></question>
 <answer>

 <para>The home page for the Cygwin project is
 <ulink url="https://cygwin.com/"/>.
 There you should find everything you need for Cygwin, including links
 for download and setup, a current list of mirror sites, a User's
 Guide, an API Reference, mailing lists and archives.
 </para>
 <para>You can find documentation for the individual GNU tools typically
 as man pages or info pages as part of the Cygwin net distribution.
 Additionally you can get the latest docs at
 <ulink url="http://www.gnu.org/manual"/>.
 </para>
 </answer></qandaentry>

 <qandaentry id="faq.what.free">
 <question><para>Is it free software?</para></question>
 <answer>

 <para>Yes.  Parts are GNU software (gcc, gas, ld, etc...), parts are covered
 by the standard X11 license, some of it is public domain, some of
 it was written by Red Hat (or the former Cygnus Solutions) and placed under
 the GPL.  None of it is shareware.  You don't have to pay anyone to use it
 but you should be sure to read the copyright section of the FAQ for more
 information on how the GNU General Public License may affect your use of
 these tools.
 </para>
 <para>Note that when we say "free" we mean freedom, not price.  The goal of
 such freedom is that the people who use a given piece of software
 should be able to change it to fit their needs, learn from it, share
 it with their friends, etc.  The GPL or LGPL licenses allows you those
 freedoms, so it is free software.
 </para>
 </answer></qandaentry>

 <qandaentry id="faq.what.version">
 <question><para>What version of Cygwin <emphasis>is</emphasis> this, anyway?</para></question>
 <answer>

 <para>To find the version of the Cygwin DLL installed, you can use
 <filename>uname</filename> as on Linux or <filename>cygcheck</filename>. Refer to each command's
 <literal>--help</literal> output and the
 <ulink url='https://cygwin.com/cygwin-ug-net/'>Cygwin User's Guide</ulink>
 for more information.
 </para>
 <para>If you are looking for the version number for the whole Cygwin
 release, there is none. Each package in the Cygwin release has its own
 version.  The packages in Cygwin are continually improving, thanks to
 the efforts of net volunteers who maintain the Cygwin binary ports.
 Each package has its own version numbers and its own release process.
 </para>
 <para>So, how do you get the most up-to-date version of Cygwin?  Easy.  Just
 download the Cygwin Setup program by following the instructions
 <ulink url='https://cygwin.com/install.html'>here</ulink>.
 The setup program will handle the task of updating the packages on your system
 to the latest version. For more information about using Cygwin's
 <filename>setup.exe</filename>, see
 <ulink url='https://cygwin.com/cygwin-ug-net/setup-net.html'>Setting Up Cygwin</ulink>
 in the Cygwin User's Guide.
 </para></answer></qandaentry>

 <qandaentry id="faq.what.who">
 <question><para>Who's behind the project?</para></question>
 <answer>

 <para><emphasis role='bold'>(Please note that if you have cygwin-specific
 questions, all of these people will appreciate it if you use the cygwin
 mailing lists rather than sending personal email.)</emphasis>
 </para>
 <para>
 Corinna Vinschen is the current project lead. Corinna is a senior Red Hat
 engineer. Corinna is responsible for the Cygwin library and maintains a couple
 of packages, for instance OpenSSH, OpenSSL, and a lot more.
 </para>
 <para>
 Yaakov Selkowitz is another Red Hat engineer working on the Cygwin project.
 He's the guy behind the current build and packaging system and maintains by
 far the most packages in the Cygwin distribution.
 </para>
 <para>
 Jon Turney is developer and maintainer of the Cygwin X server and a couple
 of related packages.
 </para>
 <para>
 The packages in the Net release are maintained by a large group of people;
 a complete list can be found
 <ulink url='https://cygwin.com/cygwin-pkg-maint'>here</ulink>.
 </para>
 <para>Please note that all of us working on Cygwin try to be as responsive as
 possible and deal with patches and questions as we get them, but realistically
 we don't have time to answer all of the email that is sent to the main mailing
 list.  Making Net releases of the Win32 tools and helping people on the Net out
 is not our primary job function, so some email will have to go unanswered.
 </para>
 <para>Many thanks to everyone using the tools for their many contributions in
 the form of advice, bug reports, and code fixes.  Keep them coming!
