system tool to enable or disable system services

 Chkconfig is a utility to update and query runlevel information for system
 services. Chkconfig manipulates the numerous symbolic links in /etc/init.d/,
 to relieve system administrators of some of the drudgery of manually editing
 the symbolic links.
 .
 In Debian, there are several tools with similar functionality, but users
 coming from other Linux distributions will find the tools in this package
 more familiar.
