Provides the &#039;spawn()&#039; function, a front-end to various platform-
specific functions for launching another program in a sub-process.
Also provides the &#039;find_executable()&#039; to search the path for a given
executable name.

def spawn(cmd, search_path=1, verbose=0, dry_run=0):
    &quot;&quot;&quot;Run another program, specified as a command list &#039;cmd&#039;, in a new process.

    &#039;cmd&#039; is just the argument list for the new process, ie.
    cmd[0] is the program to run and cmd[1:] are the rest of its arguments.
    There is no way to run a program with a name different from that of its
    executable.

    If &#039;search_path&#039; is true (the default), the system&#039;s executable
    search path will be used to find the program; otherwise, cmd[0]
    must be the exact path to the executable.  If &#039;dry_run&#039; is true,
    the command will not actually be run.

    Raise DistutilsExecError if running the program fails in any way; just
    return on success.

    # in, protect our %-formatting code against horrible death
