There isn't a way to get the stderr, but you can have the exit code returned by passing
"exit-status" as an optional parameter. This will return a list of two items: the stdout and
the error code
 
local result = [ SHELL path/to/tool.py : strip-eol exit-status ] ;
local output = $(result[1]) ;
local status = $(result[2]) ;
 
This option is documented here:
