numpy.distutils.exec_command
exec_command
Implements exec_command function that is (almost) equivalent to commands.getstatusoutput function but on NT, DOS systems the returned status is actually correct (though, the returned status values may be different by a factor). In addition, exec_command takes keyword arguments for (re-)defining environment variables.
Provides functions:
- exec_command — execute command in a specified directory and
 - 
in the modified environment.
 - find_executable — locate a command using info from environment
 - 
variable PATH. Equivalent to posix
whichcommand.

Known bugs:
- Tests, that send messages to stderr, fail when executed from MSYS prompt because the messages are lost at some point.
