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.

I think what is missing in all these suggestions is a clear statement 
that for Cygwin's purposes, the cygwin DLL is considered to be the 
'kernel', so looking for the 'kernel release' gives you the DLL version. 
I think that leap is totally non-obvious.

Do you think it would help if this FAQ entry were changed to read:

1.5. What version of Cygwin is this, anyway?
     To find the version of the Cygwin DLL installed, you can use any of the
Cygwin commands uname -a, uname -srvm, head /proc/version as on Linux, or
cygcheck -V. Refer to each command's --help output or the Cygwin User's Guide
for more information.

and please make any further comments, feedback, or suggestions you think would
help with this entry.

Running the suggested commands with their --help options would have shown you:

$ uname --help
Usage: uname [OPTION]...
Print certain system information.  With no OPTION, same as -s.

  -a, --all                print all information, in the following order,
                             except omit -p and -i if unknown:
  -s, --kernel-name        print the kernel name
  -n, --nodename           print the network node hostname
  -r, --kernel-release     print the kernel release
  -v, --kernel-version     print the kernel version
  -m, --machine            print the machine hardware name
  -p, --processor          print the processor type (non-portable)
  -i, --hardware-platform  print the hardware platform (non-portable)
  -o, --operating-system   print the operating system
      --help     display this help and exit

I note that you removed the bit that you actually wanted. 

v is NOT the same as V, you are in a case sensitive context.

If you had read the manual, you would have seen it says what I have said, and your ire and attitude are unnecessary, albeit understandable.

Always be nice first, you will find people (and we are just people) are just trying to do their best, mistakes will be rectified and attitude will usually get you ignored, you have been lucky this time.

cygwin is a package, not a program, so cygcheck -c cygwin will help; 
also did you try uname?

How to check cygwin version?

[Jeffrey Walton]

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?
