Monitor system status during Gentoo emerge. This is likely a bit system-specific and some things may not work out-of-the-box. This will probably mostly mean the CPU temperature display. A setup-agnostic implementation of that is hoped for at some point.
Requires root to read portage logs. Might even work with sudo -u portage.
The second option should be more secure, or less likely to break something.
Output of the monitor in action as of commit c6ca17b. If that commit is no longer current, this output may not be current. I will keep updated between large revisions, otherwise this is just a general feel of the monitor.

No special setup required for this one. However, a Bash-compatible shell, genlop, lm_sensors, and of course emerge are required to exist on the system. This will only work on Linux systems with the Portage package manager installed. Geared towards Gentoo Linux, it may work Bedrock, Mandrake, or derivatives.
