cyg-apt is like apt and makes installing cygwin packages a lot more friendly. I’ve always disliked the clunky setup program that comes with cygwin so this is a really nice improvement.
assuming you have cygwin, wget and python installed
cd /bin
wget http://www.lilypond.org/~janneke/software/cyg-apt
chmod a+rx cyg-apt
cyg-apt setup
cyg-apt update
for more detailed instructions see cygwin-setup
