Tomcat is the Java Servlet / Java Server Page environment produced
by the Apache Foundation's Jakarta Project.  Tomcat can be run as a
standalone web server with Servlet and JSP support, or using Apache
Server as its web server via the mod_jk Apache module (www/ap-jk).
This is the Tomcat 5 package, which is a Java Serlet 2.4 and JSP
2.0 server.
Tomcat 5.5 supports the same Servlet and JSP Specification versions
as Tomcat 5.0.x, with improved performance, stability, and total
cost of ownership.
