New in version 2.4.
The subprocess module allows you to spawn new processes,
connect to their input/output/error pipes, and obtain their return
codes. This module intends to replace several other, older modules
and functions, such as:
os.system
os.spawn*
os.popen*
popen2.*
commands.*
Information about how the subprocess module can be used to
replace these modules and functions can be found in the following
sections.
Release 2.5.2, documentation updated on 21th February, 2008.
