Juta (Java Usenet Traffic Analyzer) is a Java (1.2 or higher) command line program that reads a text file with Usenet postings, and creates an HTML file with statistical information of those postings. This includes a list of the longest threads, authors with most postings, operating systems and newsclients used, and more. The inclusion of person-related information can be turned off to ensure privacy. The program is distributed as an executable JAR that also contains the source code. Also included in the distribution are several tools to process news postings: sort and count them, remove duplicates, list information on postings, grep and filter them.
