Siphon

Siphon is an output stream formatter, used primarily as a means to prefix output from a program. Siphon can format data piped into it, or it can spawn a process and format that output. When siphon formats the output of an exec'd command, it sets up a PTY and resizes the terminal to accommodate the prefix.
