Capto can be downloaded from http://www.twg.org/capto/
The original forum thread about it is here: Capto for Tablo (CLI Grabber)
Capto can be used without wrapto. Wrapto just adds more functionality. You shouldn’t need to know any perl to use the utility. Just copy the source blurb into a text editor, save, and change the executable bit so you can run it like a program - from a terminal just do chmod 755 /wherever/you/put/wrapto
