I want to help my friend without internet connection in installing Cygwin (Linux environment on Windows platform).

The only setup program is "setup.exe" (online).

The advice on their forum: download "release" directory from their mirror. This directory contain 2 versions of source codes and 2 binary / pre-compiled versions of each package.
There are more than 250 package.

I know about GNU license, but can Cygwin team/someone create a complete Cygwin install CD / ISO with 1 version of pre-compiled binary and no source code?

Thank you.
