 Apache Tomcat implements the Java Servlet and the JavaServer Pages (JSP)
 specifications from Oracle, and provides a "pure Java" HTTP web
 server environment for Java code to run.

 This package contains only the startup scripts for the system-wide daemon.
 No documentation or web applications are included here, please install
 the tomcat9-docs and tomcat9-examples packages if you want them.
 Install tomcat9-user instead of this package if you don't want Tomcat to
 start as a service.
