function. Do you want me to do that?

this is plain ugly. make the first arg a list of strings, and remove shell=True.
And this works on linux only. What about other platforms?

[Pooja Nihalani, 2012/05/08 22:33:03]

It only works as one string "make RUN".
It works on win, linux, mac as 'make' is from within the sdk
shell=True is required for it to work on windows.
