OK, thanks to a dejanews search I figured out that I need to say:
execvpe(execName, [execName], os.environ)
execle(execName, execName, os.environ)
and I think I even understand why -- it's so you can call an executable
with something other than the name of the executable as argv. I can
sorta see why this is useful, but it would be nice if the documentation
for exec* was a little more explicit about the nature of "arg0". A line
like: "Note: arg0 is traditionally the name of the executable, and
some executables will depend on this." would have saved me a lot of
Or have I misunderstood something?
