SnoopDos is a system and application monitor. Think of it like the Amiga equivalent to the Windows Process monitor.
Last original version by Eddy Carroll was released in September 1994.
Further updated versions were then worked on by 4 further developers with permission from the original author, and the last update, version 3.8 was released in 2003 by Oliver Roberts.
A further port of SnoopDos was released in 2007 for MorphOS.
