PostRemoteLog is a tool that allows you to send information across the network to a centralized location. Three methods are currently supported: XMLRPC, Email, and Growl. It is generally aimed at system administrators who want to keep track of information such as backup post-run scripts, network monitoring scripts, UPS information, service outages, power on/off, unexpected restarts, etc. PostRemoteLog is designed to be used in other scripts. Captured data can be analyzed and aggregated as needed.
Rbpar is a program and an accompanying library suite designed for formatting text paragraphs. In this sense, it greatly resembles the venerable Unix programs fmt and par. The difference is that rbpar sports a more modern design: it is written completely in Ruby and offers an internal API for several paragraph formatting tasks.
