 This package contains only the startup scripts for the system-wide daemon.
 No documentation or web applications are included here, please install
 the tomcat7-docs and tomcat7-examples packages if you want them.

 Install tomcat7-user instead of this package if you don't want Tomcat to
 start as a service.
