Keep in mind that Cygwin can only do as much as the underlying OS supports.Hello and welcome to the Windows 7 Forums, a community where users can discuss anything related to the this Microsoft operating system.Please join our friendly community by clicking the button below - it only takes a few seconds and is totally free.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.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.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. 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. 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.You can find documentation for the individual GNU tools typically as man pages or info pages as part of the Cygwin net distribution. Note that when we say "free" we mean freedom, not price.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.
