�ZdS(s�distutils.spawn

Provides the 'spawn()' function, a front-end to various platform-
specific functions for launching another program in a sub-process.
Also provides the 'find_executable()' to search the path for a given
executable name.
s1$Id: spawn.py 37828 2004-11-10 22:23:15Z loewis $i�N(t*(tlogiicCs�tidjot||d|�n_tidjot||d|�n8tidjot||d|�ntdti�dS(s�Run another program, specified as a command list 'cmd', in a new
    process.  'cmd' 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 'search_path' is true (the default), the system's executable
    search path will be used to find the program; otherwise, cmd[0]
    must be the exact path to the executable.  If 'dry_run' is true,
    the command will not actually be run.

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