"""cli-specific implementation of process utilities.

cli - Common Language Infrastructure for IronPython. Code

can run on any operating system. Check os.name for os-

specific settings.

This file is only meant to be imported by process.py, not by end-users.

This file is largely untested. To become a full drop-in process

interface for IronPython will probably require you to help fill

in the details.
