Also provides the 'find_executable()' to search the path for a given executable name. éN)ÚDistutilsExecError)ÚDEBUG)Úlogéc Cst|ƒ}t t |¡¡|r dS|r@t|dƒ}|dur@||d<|durL|nttjƒ}t j dkr‚ddl m }m }|ƒ}|r‚|||<z tj||d} |  ¡| j} WnHtyê} z0ts¾|d}td|| jdfƒ| ‚WYd} ~ n d} ~ 00| rtsþ|d}td|| fƒ‚dS) aRun 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.
