pipeline 0.1

Easy shell-like pipelines, with input from a file-like object

Provides a file-like interface to other system processes and shell-like
pipelines. In contrast with os.popen, the shell is not used to interpret the
commands, and the exit status of each componenet of the pipeline is availabe.
An alternative to builtin packages such as subprocess, commands, os.popen,
popen2, os.system, etc.
Examples of how to feed the pipe with a file-like object are included in the
docstrings. Requires os.fork, but does not require any threading
libraries.
