Also provides the 'find_executable()' to search the path for a given executable name. s $Id$i����N( t DistutilsPlatformErrort DistutilsExecError( t DEBUG( t logi i c C s� t | � } t j d k r1 t | | d | �nZ t j d k rV t | | d | �n5 t j d k r{ t | | d | �n t d t j � d S( 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. t posixt dry_runt ntt os2s1 don't know how to spawn programs on platform '%s'N( t listt ost namet _spawn_posixt _spawn_ntt _spawn_os2R ( t cmdt search_patht verboseR ( ( s' /usr/lib64/python2.7/distutils/spawn.pyt spawn s c C s> x7 t | � D]) \ } } d | k r d | | | <q q W| S( s� Quote command-line arguments for DOS/Windows conventions.
