best way to launch (a series) of other (non gnustep) programs

[Matthew Weinstein]

Is there a way to launch a program (I'm trying to use graphviz dot 
and then gv to look at the output) without knowing its path (i.e., 
just have the computer use the current $PATH rather than me supply an 
explicit one). These are non GNUstep apps, obviously. It just seems 
very unportable to hardcode the locations of these programs. Also is 
NSTask the way to go with this?
