Gotcha! is a small (well not so small anymore ;-) utility for OS/2 which allows to easily capture windows, window interiors, parts of the screen or the whole desktop and save them to disk or clipboard as a picture (in several file formats if OS/2 Multimedia is installed; otherwise only BMP format).

It has options for serial capture (automatically taking a capture every n seconds) and batch mode (take a capture, save and exit).

I wrote Gotcha! mainly because all other screen capture programs for OS/2 that I found were either really old and/or part of some big other program and/or buggy and/or not free.
