:: Specify default launcher for Cygwin: conemu mintty cmd
:: If specified launcher is not available, defaults to next available one in the following order: conemu mintty cmd
set LAUNCHER_CYGWIN=

:: Comma-separated list of the packages to be installed automatically: https://cygwin.com/packages/package_list.html
:: You will be able to install other packages later with apt-cyg if INSTALL_APT_CYG is set to yes below
set CYGWIN_PACKAGES=bind-utils,inetutils,openssh,vim,whois

:: You can choose the closest mirror: https://cygwin.com/mirrors.html
set CYGWIN_MIRROR=

:: Set proxy, if required, in the following format:	proxyip:port
:: Applicable to installation process only
set PROXY_HOST=

:: Override OS architecture, if required: "32" bit or "64" bit system. Leave empty for autodetect
