I think the documentation leaves a lot to be desired... I'm trying to
tell someone what version of Cygwin I am using.

There's a FAQ item at
https://cygwin.com/faq/faq.html#faq.what.version. It gives this
useless advice:

   To find the version of the Cygwin DLL installed, you can use uname
   as on Linux or cygcheck. Refer to each command's --help output and
   the Cygwin User's Guide for more information.

OK, let's try it:

$ cygcheck -v
Usage: cygcheck [-v] [-h] PROGRAM
       cygcheck -c [-d] [PACKAGE]
       cygcheck -s [-r] [-v] [-h]
       cygcheck -k
       ...

OK, -v is what we need:

$ cygcheck -v cygwin
cygcheck: could not find 'cygwin'

OK, another failure.

RTFM does not work. Why the hell don't you just state how to check the
god damn version?

#!/bin/bash

function EmitHelp() {
expand -t4 << __End_of_Help__

Emits various info about the cygwin installation.

By default, just emits the main version number on one short line,
then quits.  (For many purposes, that is sufficient.)

With -v (verbose) does the following stuff, too:

Then emits a couple of envars of interest, and the timestamps of a few files.

Then runs 'cygcheck -csv' into a temp file, and greps the output to display the
version and status of various cygwin packages that Karl considers "interesting".

With -t FILENAME, uses the arg as the temp file, and does not delete it.

With -r, gives cygcheck the options that make it dig around in the Windows
Registry looking for extra stuff about cygwin.  Slow, and rarely needed.
