Unfortunately, the instructions in FAQ # 2.15 "How do I install 
snapshots?" is not completely clear.  It says that one should first 
close all Cygwin applications and shells.  But then it says to "run" a 
sequence of commands:

   cd /
   tar .......
   cd /tmp
   tar ......

Now given that I was supposed to exit Cygwin, presumably these commands 
are to be run from a Windows command prompt.

But then to what does root directory "/" refer?  To the Cygwin root? 
And if so, where should I have put the downloaded 
cygwin-inst-YYMMDD.tar.bz2 ?  And if "/" does not refer to the Cygwin 
root, to what does it refer?

If the commands are to be run within Cygwin, on the other hand, then 
that would seem to contradict the first instruction, namely, to close 
all Cygwin applications and shells.
