[Zope] shell commands: zShellScripts or external methods?

[David Siedband]

I'm writing a web interface for a C++program and I need to construct 
and issue a shell command to start the job, passing a few options on 
the command line.

something like
./analyzeSeq -i /tmp/ara03_45.txt -d .003 -k 1.22

Is it a better idea to use external methods and os.* or zShellScripts 
for this?

thanks
