If you've never installed Cygwin then this is going to be a bit
more difficult, but here it is anyway...

You'll need a cygwin package that has the snapshot files built in.  To
do this, unpack the files from the current cygwin package into a
temporary directory, then unpack the snapshot files into the same
directory (which updates the directory with the filesfrom the snapshot),
package the directory up again as a tar.bz2 file, note the md5sum and
change the entry in setup.ini for the package to have the correct
filename (if you've changed it) and checksum.  You should then be able
to use setup.exe just fine to install a new Cygwin instance.


Here's a Makefile that will do the packaging, adjust the locations:
