So, I lost my cool shortcut to take screen shots with ease on Windows, turning them into both clear and tiny images. In PNG format of course. How did I lose it? Hard disk crash. And the backup I thought I had on my home PC was on the previous hard drive, which is still OK, but in a pile somewhere, and not worth looking for. Cue the backup DVD search.
Bingo, found it on the first one - labeled "\cygwin \download \home \sfu \tmp" from 29-Dec-2007, just before the home hard drive renovation.
There it was, under /usr/local/bin, below D:\CYGWIN. And /usr/local/etc had
-rwx------+ 1 jspath ???????? 659 Aug 21 2003 colormap.ppm
Which is a Portable Pixmap file containing the magic pixels known somehere long ago as the set optimized for Netscape.
$ file /usr/local/etc/colormap.ppm
/usr/local/etc/colormap.ppm: Netpbm PPM "rawbits" image data
Anyway, that fits into the cliptopng script I wrote to go from "[prt sc]" to writing a PNG file in one swoop. Beats launching Word or MSPaint and trying to shrink the image file.

There's probably a better way to do this, but it works for me.
The first step requires winclip.exe. Fortunately I had that restored under c:\bin.
The other files are from the NetPBM library, which you can get for Windows via http://www.cygwin.com/.
The gif2png.exe may be another non-NetPBM utility, necessary because I couldn't find a direct PNG writer. It may exist now, but this runs in a second or so and I'm unmotivated to change it.
Here's the Winclip license feedback:

To restore, I just dragged the whole local directory from DVD backup to hard drive. A lot easier than clicking on SETUP.EXE, etc.
