This doesn't work in the general case, as not all snapshots are uploaded
as test packages. Plus you'd have to wait while your favourite mirror
picked up the new package.
Sadly, parsing the HTML is the only way to go right now. This is very
error-prone, as any assumption you make about the structure of the HTML
could change with no notice. The following works (as the snapshots page
stands) by extracting the date from one of the filenames:
wget -q -O - http://cygwin.com/snapshots/ | egrep
"cygwin1-[0-9]*.dll.xz" | head -n 1 | sed
This is about as fool-proof as I can make it. It assumes nothing about
the HTML, so it should survive a fairly substantial change to the web
page. Provided we don't change the format of the filenames, the above
stands a chance of working. YMMV.
