Automated Cygwin installation and configuration.
It appears a reply by Ralph Hempel in the Re: Customizable cygwin setup.exe thread is what started this project.
Will Rogers then published a gist called install.bat.
RT Wolf then published the rtwolf/cygwin-auto-install repo to GitHub.
Finally, Olivier Dagenais forked the aforementioned repository and incorporated some ideas from Tomek Bujok's Babun project and Stephen Jungels's apt-cyg tool.
